This approach has helped them establish a reputation as some of the best cataract surgery Orange County specialists, as well as leading Visian ICLs experts.\n- Optical Coherence Tomography\n- Optos® OPTOMAP™\n- Heidelberg Retina Tomograph (HRT II)\n- Visual Fields\n- ZEISS® IOL Master™\nOptical Coherence Tomography\nOptical coherence tomography (OCT) is a very sensitive non-contact diagnostic test commonly used to detect glaucoma, retinal thickening associated with macular degeneration, and numerous other retinal conditions.\nOCT works by using light waves to create a high-resolution cross-sectional image of the inner structures of the eye in order to detect retinal changes below the surface of the retina such as macular holes, macular edema, and other eye conditions. OCT can reveal much more detail to the inner workings of the retina when compared to a simple dilated exam for patients with macular degeneration, glaucoma, diabetic retinopathy, and many other retinal conditions. Because of this, doctors can more specifically assess and diagnose these conditions.\nA leading tool available to doctors during the initial screening to detect eye diseases and disorders is the Optos® OPTOMAP™. The image created by the OPTOMAP™ provides the doctor with a digital wide-field of view of the patient’s retina, which is helpful in detecting eye diseases and disorders that may be missed using conventional retinal examination techniques. With this new tool, patients have the benefit of not necessarily needing dilation to exam the retina while at the same time providing a much better level of detail in the retina to follow changes in retinal conditions.\nHeidelberg Retina Tomograph (HRT II)\nThe Heidelberg Retina Tomograph is a cutting-edge medical device used by doctors to examine the rear portion of the eye for the presence of various retinal diseases and disorders such as glaucoma. The HRT II uses a laser to scan the patient’s optic nerve head, producing three-dimensional images of the optic disc within the eye, and calculating the thickness of the retinal nerve fibers. Defects in the fibers can be an early telltale sign that a patient is developing glaucoma. The HRT II allows our doctors to apply statistical analysis to the optic nerve that is suspect for early glaucoma damage. The HRT II test takes less than 15 minutes. Because early detection of glaucoma is imperative in preserving vision, the HRT II can be an invaluable tool.\nThe visual field is the total area in which objects can be seen in the peripheral (side) vision while the eye is focused on a central point. A visual field test measures how much “side vision” a person has. Advances in computer technology have greatly enhanced the ability of doctors to measure a patient’s visual field.\nHumphrey Visual Field Analyzer\nThe Humphrey Visual Field Analyzer is a computerized machine used by doctors to measure the visual fields that are visible to a patient. Analysis of visual fields is important to the proper diagnosis of glaucoma. The machine uses flashing lights cast inside a viewing hood to determine how well a patient can see. The lights appear in different vision areas, and with the patient’s head remaining still during the test, the patient’s visual field can be determined.\nZEISS® IOL Master™\nThe ZEISS® IOL Master™ is a device that uses partial coherence interferometry to measure the eye, calculate the dimensions and surface curvature, and evaluate the power of the intraocular lens, all of which are necessary before cataract surgery or removal of the natural lens can be performed. Measurements can be made quickly and efficiently without contact with the eye, which eliminates the need for anesthesia and greatly reduces the risk of corneal abrasions, eye infections and contamination of instruments. IOL Master™ technology, widely used in clinical ophthalmology, is much more accurate and predictable for choosing cataract replacement lenses, such as ReStor and Tecnis Multifocal. This technology also allows Clarity Eye Group’s surgeons to provide their Crystalens Orange County patients with the best possible vision correction results.\nContact Clarity Eye Group Today\nAt Clarity Eye Group, we are committed to providing our patients with the best and latest technology available in the science and practice of eye care. Using the most up-to-date techniques, equipment, and procedures, we are able to achieve consistently impressive results for our Orange County LASIK surgery and cataracts patients.

It’s not too much to say that this is becoming the new normal.\nIn fact, you’re probably already mixing and matching lenses. For instance, if you place monofocal lenses, you’re likely not putting the same power lens in each eye. If you put a 19D monofocal lens in the left eye and a 20D monofocal lens in the right eye, the lenses are of different powers.\nIn this article, I’ll share the success I’ve had in mixing and matching intraocular lenses (IOLs), specifically using the TECNIS Symfony OptiBlue IOL from Johnson & Johnson Vision. I’ll discuss why this lens works so well, as well as patient selection.\nBest of Both Worlds\nSeveral years ago, when the first-generation presbyopia IOLs became available, surgeons didn’t mix and match lenses. Surgeons implanted the same lens in both eyes, and patients had to accept the vision that those lenses provided.\nNow, surgeons have a wealth of options available, including multifocals, trifocals, bifocals, and extended-depth-of-focus (EDOF) lenses. In my practice, my happiest patients are those for whom I’ve mixed and matched different lens technologies. Doing so provides them the best of both worlds in both vision quantity and quality.\nHigher-add multifocals or multifocals mixed with EDOF technology, such as the TECNIS Synergy IOL, provide excellent quantity of vision. For near vision especially, the TECNIS Synergy can provide a “best-in-class” result, with patients routinely J one plus.\nHowever, the patient might not have quality vision at every single focal point. When I have implanted the Synergy bilaterally, patients loved their intermediate and near vision, and most were pleased with their distance vision as well. However, some patients were less pleased with the quality of their distance vision, specifically with contrast and sharpness.\nI’d had experience using the TECNIS Monofocal 1-Piece IOL (ZLB00), which is the previous-generation TECNIS multifocal +3.25D in the nondominant eye and the first-generation Symfony in the dominant eye, with good results. I had not had much luck with other brands of multifocals or trifocals on the market.\nWith the launch of the Symfony OptiBlue presbyopia-correcting IOL in September 2022, which is the next-generation EDOF lens, my ability to mix and match lenses increased further. Like the Synergy, the Symfony OptiBlue IOL uses InteliLight, which combines three J&J proprietary technologies (See Trio of Technologies).\nBy mixing and matching these two lenses, I give my patients the benefit of the overall quality of vision and the quality of distance vision of the Symfony OptiBlue, combined with the excellent near vision that the Synergy provides.\nI also find the wider landing zone and wider sweet spot of the Symfony OptiBlue helpful. The Symfony OptiBlue, which also comes in a toric version, seems more tolerant of residual refractive error compared to the Synergy. With the Synergy, I find patients need to be very close to plano to experience the maximum benefit (See Symfony Specs).\nHaving implanted several hundred lenses using the Symfony OptiBlue in the dominant eye and the Synergy in the nondominant eye, I have seen remarkable results. I have not explanted any lenses, indicating high patient satisfaction.\nUsing the Symfony OptiBlue in the dominant eye and the Synergy in the nondominant eye suits the needs of just about all of my patients and has become my go-to solution. That’s the case especially for any patients who say they don’t want to wear reading glasses. By and large, most patients who are paying a premium for presbyopia-correcting IOLs don’t want to wear readers any of the time, so we try to reduce that as much as possible.\nFor example, imagine a myopic patient who is accustomed to excellent near vision without glasses. When time comes for cataract surgery, that patient may want really excellent near vision, say in the J one range. In that patient, mixing and matching the Symfony OptiBlue in the dominant eye and the Synergy in the nondominant eye can provide excellent results. This combination provides excellent distance and intermediate vision and very functional near vision.\n- Optic diameter: 6.0 mm\n- Overall diameter: 13.0 mm\n- Center thickness: 0.7 mm (20.0 D)\n- Powers: +5.0 D to +34.0 D in 0.5-D increments\n- Material: UV-absorbing hydrophobic acrylic with violet-light filter\nSource: Johnson & Johnson Vision\nIn contrast, some patients may want excellent distance vision and are willing to wear reading glasses some of the time. In that case, I may implant the Symfony OptiBlue in both eyes.\nPatients who need excellent near vision for up-close tasks are also happy with this mix-and-match strategy. That includes patients who are voracious readers, needlepoint makers, and sewers and knitters.\nConversely, I tend to avoid using this solution with patients who need excellent night vision, such as those who earn a living driving at night. Even though patients can become accustomed to halo and glare after a few months, I avoid using a multifocal IOL for them. In these patients, I might consider using nondiffractive designs that provide minimal nighttime halo and glare.\nCustom Lens Replacement\nBesides cataract patients, I mix and match the Symfony OptiBlue and Synergy in my custom lens replacement patients. Specifically, the strategy works well in patients who want freedom from glasses but aren’t suitable candidates for laser vision correction. These are hyperopic patients who are in their 40s or 50s and have decent distance vision but notice that it’s starting to fade, and they have very poor near vision without reading glasses. These patients have been very happy with this solution.\nTRIO OF TECHNOLOGIES\nThe TECNIS Symfony OptiBlue IOL is powered by InteliLight, a combination of 3 Johnson & Johnson Vision technologies: violet-light filter, echelette design, and achromatic technology. The technology was first introduced in the TECNIS Synergy IOL.\n- Violet-light Filter: Blocks the shortest wavelengths of light that produce the most light scatter, helping to mitigate halo, glare, and starbursts, and minimizing visual disturbances when driving at night\n- Echelette Design: Helps to reduce light scattering and halo intensity, making it easier to see digital devices\n- Achromatic Technology: Corrects chromatic aberration for better contrast day and night and superior performance across every distance\nSource: Johnson & Johnson Vision\nSteps for Success\nPrior to implanting lenses, my practice will perform a full tear film analysis with inflammatory markers. To ensure the patient has a clean macula, we perform a macular scan and a widefield Zeiss Clarus (Carl Zeiss Meditec) image on every workup.\nAlso, we perform topography and tomography to ensure that the astigmatism is regular. We use 2 different diagnostic devices to accurately determine the magnitude and meridian of the astigmatism. We avoid a mix-and-match solution with patients who do not have a regular astigmatism.\nFinally, we strive to ensure that the patient will be happy with our solution from a psychological perspective. If a new patient is complaining bitterly about his or her first eye that was done by another doctor, yet it looks fine, and the complaints are out of proportion to what we see in the clinical exam, we expect this may not be a suitable patient for a multifocal lens.\nToday, patients live in a near-vision world, relying constantly on digital devices, such as phones, tablets, and computers. As we care for cataract patients, we can restore their near vision, as well as provide excellent intermediate and distance vision. Combining the latest lens technologies provides a sound strategy for our cataract patients. ■", "domain": "optical_engineering"}

The Regal 100ED brings all of the features of the other M2 scopes to the table but adds a lens diameter that offers greater light gathering abilities than either the 65 or 80mm versions. As a result, it provides some of the clearest images of birds, targets, and even limited astronomy viewings possible through this line while providing the level of quality construction and affordability that you would expect from Celestron.\nThe Celestron Regal 100ED possesses specs that in many ways match those of the other members of the M2 line. These features offer a look into what makes this line of spotting scopes such a desirable and well-reviewed set of scopes. At the same time, it offers a larger lens and better field of view that promises even better images for serious nature hobbyists to enjoy. Following are a few of its most important features:\n• Diameter of objective lens: 100mm\n• Optical coatings: Fully multi-coated\n• Dimensions: 19.2in. X 4.8in. X 4.8in.\n• Weight: 8.6 lb.\n• Eye relief: 20mm\n• Magnification: 22x-67x\n• Angular field of view: 1.9-.9°\n• Close focus: 26.2ft./8m\nCelestron Regal M2 Spotting Scope Review\nOne of the most unique and useful features of each of the scopes in Celestron’s M2 line is the ED glass that the company uses in the objective lens. This glass, which stands for “extra low dispersion glass,” functions by limiting the extent to which light is scattered as it passes through the lens. The result is that the light remains focused, improving the sharpness and clarity of the images and cutting down on color distortion. The improved accuracy of the view lends itself to high-accuracy activities such as target shooting and bird watching. While ED glass is often available in more expensive scopes, its presence in the more affordable Celestron M2 scopes adds significant value and allows these scopes to produce images that mimic those provided by pricier viewing instruments.\nThe ED glass in the Celestron Regal 100ED stands up under actual usage by reviewers. They report that the images the scope provides exceed their expectations for a scope as inexpensive as the Celestron Regal is. They even report enjoying accurate views at up to several hundred yards. Even target shooters, whose hobby requires superior viewing abilities, report being satisfied by the Regal’s performance.\nIn addition to ED glass, the Regal 100ED’s optical abilities are enhanced by the use of full multi-coated optics. This term refers to the fact that all of the lenses in the spotting scope have been coated with several layers of substances that sharpen and focus the light as it passes through the lens. The result is that these coatings further cut down on distortion in the resulting images and contribute to their overall excellence.\nIn addition to strong optical performance, the Celestron Regal 100ED is defined by comfort and ease of use. Reviewers find that the scope cuts down on eye strain and allows them to enjoy their viewing adventures for long periods of time without discomfort. Part of the reason for this comfort is the 20mm eye relief, as well as the fact that the eyepiece is adjustable and the eyecup is comfortable once adjusted to the viewer’s satisfaction. In addition, the Regal 100ED comes with a tripod mount that offers versatility and choice in how the scope is mounted. The mount, which receives praise from reviewers, allows the scope to be attached to the tripod in any one of four ways in order to allow the viewer to choose the most comfortable and practical arrangement possible for their viewing session.\nFinally, reviewers note that the Regal 100ED is sturdily constructed. Its magnesium alloy body allows for a lighter feel without compromising its strength. A limited lifetime warranty ensures that consumers can purchase the scope with the confidence that any issues they encounter will be speedily resolved. The result is a strong, high performing scope that will appeal to consumers who want to enjoy nature views, bird watching, target shooting, and other spotting activities on a budget.", "domain": "optical_engineering"}

Let’s take a detailed guide on Beam Splitters.\nThe most basic of these types of elements is the plate beam splitter in which an input beam is split into two different beams. The two new beams are the transmitted and the reflected beams respectively and their directions are usually orthogonal to each other, although that will depend on the input beam’s angle of incidence. The input beam characteristics like beam size and divergence are retained in the two new beams.\nAnother type of beam splitter that is based on a different operating concept is the microlens array which consists of a series of small lenses, or lenslets, that share the same size and radius of curvature. An input beam is partitioned into many smaller beams that are brought to focus at the focal plane at each lenslet.\nAnother type of beam splitter that surpasses in versatility and efficacy both elements from above is the diffractive beam splitter. Unlike the previous beam splitter elements that work on the principle of light refraction, a diffractive beam splitter exploits the wave nature of light so the output transmission can be understood to be an interference effect.\nIn a diffractive beam splitter the input beam is turned into an array of multiple beams that can be arranged in any geometrical configuration. Each new beam shares the same characteristics of the input beam. Thus, the size and inherent divergence of the new beams is the same as the one from the input beam. Moreover, the angular orientation, or the spatial separation, among the new beams can be designed to any desired value.\nGiven all these remarkable features, a diffractive beam splitter finds applications in many industrial and academic fields. For instance, one of the extra beams generated by the beam splitter can be designed to be with very low power to be used for monitoring laser power in the system, avoiding having to measure power directly on the processing beam. Another totally different application can be found in aesthetic treatments in which a multi spot diffractive beam splitter generates a closely packed array of beams at the focal plane of a medical laser. Once on the patient’s skin, this irradiance pattern results on a larger area and, even more important, on a more efficient healing process. This stems from the presence of the gaps among the many spots that facilitate epidermal cell migration.", "domain": "optical_engineering"}

MEGA O.I.S. zoom lens, designed for Micro Four Thirds cameras, packs a ton of quality into a small, jewell-like package.\nThe optic weighs a mere 4.76 ounces and is measures a svelte 2.19\" x 1.97\" (DxL). Yet, its effective focal length is 70mm-200mm, perfect for outdoor field work. When mounted on Panasonic mirrorless cameras, the optic's built-in image stabilization is rated at 3 stops.\nOn Olympus bodies, photographers have the option of using sensor-based stabilization or optical MEGA O.I.S. They can switch to optical in the \"gear\" menu > \"C\" Release > Lens I.S. Priority. Since the optical stabilizer is quieter than the sensor-based alternative, there may be situations where Olympus owners want to take advantage of this feature.\nThe Panasonic lens maintains its compact size by retracting. To use it, twist to the right to move it into zooming position. The nicely-damped zooming ring keeps the barrel in place regardless of shooting position. The manual focusing ring also feels good. Like the image stabilization, switching to manual focus happens in the camera's menu. There are no switches on the lens itself.\nOutdoors, focusing is fast and accurate. Indoors, the lens may hunt for a second or two before confirmation. This highlights the fact that the Panasonic 35-100mm f/4-5.6 is an outdoor lens. Its maximum aperture and focusing capability will not satisfy the indoor, existing light photographer. Outside, however, the optic is a joy to use.\nImage quality is excellent edge to edge, with slightly better performance in the center. Distortion and chromatic aberration are also well-controled, a surprising performance for such a compact, affordable zoom.\nThe Panasonic 35-100mm f/4.0-5.6 zoom lens was released in late October for $397. It's styled to compliment the Panasonic GM line of mirrorless bodies. But it looks great on the Olympus cameras too. Its metal barrel construction and mount feel solid, and the swift focusing via the stepping motor inspire confidence. The optical performance is very satisfying.\nBottom line: I love this lens. It's a quality optic that's easy to carry with me.

Widely used in the telecommunication industry, in the 1980s they started to be used in astronomy to couple light from the telescope focus to highly specialized and sophisticated instruments located elsewhere, eg. in the observatory basement (Heacox 1986).\nFibers typically have three layers, the core, cladding and buffer (Figure 1).Fibers and operate on the principle of total internal reflection (TIR) : the core and cladding are made from glass, and the refractive index of the core is higher than that of the cladding to enable TIR. The role of the buffer, on the other hand, is to provide protection to these fragile glass strands.\nFigure 1 : Optical fiber layout\nFor an extreme RV precision instrument like NEID, optical fibers offer various advantages, some of these are : –\n- By decoupling the instrument from the telescope focus, they allow for the instrument to be quite heavy and sophisticated (NEID weighs about a couple metric tons!) . Further, it allows the instrument to be housed in the basement of the WIYN telescope in a room with temperature control to the level of 1 degree Celsius or better.\nFigure 2 : WIYN basement showing the location of NEID, the laser frequency comb and the electronics rack/s.\n- Having the instrument in the basement also means a near constant gravitational vector for the instrument. An instrument at the Cassegrain focus of the telescope would move constantly as the telescope tracks the target. This is important to prevent a variable sag or bending of the optics or mounts in the instrument.\n- The fiber provides a degree of scrambling for the light. This means that illumination at the output end of the fiber is less sensitive to the the location of the star on the input face. This is important to average over any illumination changes or guiding errors of the telescope (See Halverson & Roy et al. 2015).\nNEID Fiber Train\nShown below is the entire fiber train for NEID. Here, we shall go over some of the components.\nFigure 3 : Overview of the NEID fiber train\nFiber puck and polishing\nNEID has two different operating modes, High Resolution (HR) for the brighter targets for maximum RV precision, and High Efficiency (HE) for the fainter targets, with higher throughput. To enable this, the HR mode has smaller fibers (64 micron core) while the HE mode fibers are bigger with ~100 micron cores to allow for higher efficiency.\nFor the HR mode we have three fibers – Sky, Science and Calibration ; whereas the HE mode has only Science and Sky (bigger fibers take up more detector real estate). The Science fiber, of course, is where the stellar light enters the instrument. The Calibration fiber in the HR mode is used for simultaneous wavelength calibration of the stellar spectrum. The Sky fiber is used for a variety of telluric corrections.\nThis combination of HE and HR mode fibers are inserted into a fused silica puck manufactured by Femtoprint using a combination of a femtosecond laser and hydrogen fluoride etching. This is shown in Figure 4.\nFigure 4 : F. Silica puck from Femtoprint. It shows the 5 bore holes for the 3 HR and 2 HE fibers, along with their conical inserts to ease the process of fiber insertion.\nAfter inserting the fibers in the puck they are epoxi-ed into place using Epotek 301 – 2; once this epoxy dries, we polish the puck. For the polishing we use a custom made polishing jig which attaches the puck shown above to the polishing arm on the table. It then moves in a ‘figure of 8’ pattern to polish the fiber. To do this we start with a coarse 60 um grit, and progressively move to smoother grits as 12, 5, 3, 1, 0.3 um grits of silicon carbide, aluminium oxide and diamond.\nFigure 5 : Video clip showing the polishing mechanism\nOnce we polish the puck, and grind away all the epoxy, the resultant puck looks like shown below in Figure 6. We need to get a good surface smoothness to prevent FRD deterioration from roughness on the end surface of the fiber.\nFurther for NEID we plan to stick a plano – convex lens onto this polished puck surface as part of the input optics focal ratio changer, and to protect the fiber surface from damage.\nFigure 6 : Polished NEID puck\nThe fiber that goes inside the instrument in this puck is circular. However, the rest of the fiber train is octagonal. Therefore we splice the circular fiber on to the octagonal fiber face, which basically means fusing them together.\nTo do this, we first strip away the polyimide buffer shown in Figure 1. We do this using a 3SAE plasma arc fiber stripper. This creates a plasma arc between three electrodes located 120 degrees apart. The fiber is placed between them and slowly gets stripped off of its buffer. Shown in Figure 7 is the fiber being stripper for the HPF fiber.\nFigure 7 : Clip showing an HPF fiber being stripped\nAfter this we use a diamond blade cleaver to cleave (cut) the stripped fiber. The stripped fiber has about a 4 -5 mm patch of exposed fiber (only core and cladding). This is then spliced on to the patch of fiber using a device similar to the stripper – it uses three electrodes to create a plasma arc which fuses the two ends together. Below in Figure 8 is shown a test fiber after being spliced. Figure 9 shows the spliced HPF fibers in a splice sleeve and heat shrink tubing to protect the splice.\nFigure 8 : Splice test for NEID fibers\nFigure 9 : Splice protection for the HPF fibers. NEID fibers will be similar\nModal Noise Agitator\nThe optical fibers being used for HPF and NEID are multi-mode, and hence support a finite number of modes. Hence the light emerging from the fiber contains an interference pattern between the many modes traversing across the fiber. This is called modal noise, or “speckle noise”. For big fibers, there are enough modes that the statistical variation in the change in energy distribution of modes is insignificant. However, in the presence of smaller fibers as in NEID, or the use of slits or fiber slicing, modal noise needs to be mitigated for the measurement of precise radial velocities.\nThe HPF science and sky fibers are agitated using the device shown below; whereas for the calibration fiber we use a combination of a mechanical agitator and an integrating sphere. This is because the problem gets exacerbated for the calibration fiber which uses the laser frequency comb – a highly coherent light source.\nFor an introduction to understand Modal Noise, refer to – Baudrand and Walker 2001, McCoy et al. 2012, Mahadevan et al. 2014.\nFigure 10 : Clip showing the fiber agitator for HPF. NEID will use a similar one.\nDouble Scrambler – Ball Lens\nFibers provide some degree of scrambling the spatial location of the input spot (Heacox 1986), however for precision RV application, this needs to be improved by many orders of magnitude. For HPF and NEID we use the ball lens described in Halverson & Roy et al. 2015. Basically, our scrambler is a simple ball lens with refractive index ~ 2, which exchanges the far and near field of the fiber. The two ends of the fibers are placed inside a v – groove block (as shown in Figure 11), and butt coupled to the ball lens which is in the middle.\nThis ball lens is based on the double scrambler concept proposed early in the days of fiber-fed spectroscopy by Hunter and Ramsey (1992) at Penn State!\nFigure 11 : Showing the ball lens setup during prototyping. Figure Credit : Halverson 2015\nFigure 12 shows how the scrambling performance improves for an octagonal fiber over a circular, further the gains for the double scrambler, and for the spliced system.\nFigure 12 : Showing the scrambling gain.\nThe top panel shows the input face of the test fiber. Whereas the bottom one shows the near field. Figure Credit : Halverson 2015.\nThis entire system forms the instrument optical fiber package. There are some additional systems involved for the acquisition camera as well as the exposure meter, which are not discussed here. Essential to ‘carry’ the photons from the telescope or calibration sources into the instrument, the fibers are like the circulatory system of the instrument! (In this analogy, the electronic system is perhaps the nervous system, communicating information from the sensors and heater to the system computer.)", "domain": "optical_engineering"}

Busch Stadium is now one of 18 Major League Baseball stadiums with LED lighting technology.\nThe St. Louis Cardinals partnered with PLANLEDTM to install the lighting system. Abernathy said it has the highest, true-to-life color rendering in an outdoor sports venue.\n“Increasing the quality and intensity of our light by about 25%,” said Abernathy.\n“We are going to have a color rendering index of 90% which has never been done at an outdoor facility.”\nThe system provides 90% of the quality of natural light that allows uniformity by reducing shadows and glare. Whether fans are watching the game in stadium seats or from home, the lights are expected to improve the visual experience.\n“You may see the ball better. You’ll see the colors much better,” said Abernathy. “With this 500k light that the LED system will put out, reds will pop out brighter and greens will be greener.”\nHe said the advanced nature of the LED lights improves broadcast quality for viewers at home since the system is HD compatible and 4K ready. Ultra-slow motion replays will no longer have the light flickering.\nAbernathy detailed some of the advantages for players on the field.\n“Certainly from a scientific standpoint, we met all the test requirements,” he said. “The glare is under control, which is one of the key things when it comes to providing brightness. With the 680 light fixtures, we can provide different angels of aiming and that becomes the key to controlling glare to make sure you’re not shining directly into a player’s eye from a location from which he might be seeing the ball.”\nThe new LED lighting technology also reduces operating and energy costs.\n“Tens of thousands of dollars every year is what it’s going to save,” Abernathy explained.\nThe system is designed to have a life expectancy of 30 years with at least a 50% reduction in the energy required to operate the field lights.\n“We won’t have to get up there every year and replace them. In fact, this particular system has a 20 year warrantee,” Abernathy said. “I won’t have to replace lights, they tell me, for as long as 30 years.”\nThe system is also capable of producing theatrical lighting effects and themes that can be programmed for home run celebrations and other special events.", "domain": "optical_engineering"}

Find the Light icon and press to open the Ambient Light sensor.\n2. Your phone has a light sensor—can you find it?\nIt’s usually located on the front face of the phone near the top. Try slowly moving your finger across the phone while you watch the sensor card on Science Journal. The sensor card is measuring lux, a unit of illumination. When the sensor card reading is close to 0 lux, you’re covering the sensor.\n3. Move your hand near and far from the sensor.\nWhat do you notice? Make observations in both meter and graph modes.\n4. Investigate the light in your environment. If you’re inside, explore all corners of the room:\nHow do artificial light sources compare to natural light from a window? What happens near a wall, under a table? Where do you find the lowest reading? Where do you find the highest reading? What happens if you place the light sensor at different angles to the light source? Does tilting the phone make a difference?\nIf you’re outside, explore the natural light from the sun and the different shadows it creates.\nWhat’s Going On?\nThe ambient light sensor measures light in lux, a measure of illumination that depends on the amount of incoming light and the area over which it is spread.\nA full moon provides about 1 lux of illumination, a typical lamp-lit living room about 50 lux, classroom lighting and sunrise and sunset about 400 lux, daylight (indirect sun) over 10,000 lux, and direct sun over 30,000 lux.\nLux is an unfamiliar unit for most of us. When we buy lightbulbs, we often shop by watts—but the wattage of a bulb doesn’t tell you how bright a bulb is, only how much energy it uses. Lumens are a better measure for light shopping; they tell you how much light a bulb will actually produce. Lux, meanwhile, tells you how much of that light arrives at a particular area.\nSince light spreads out as it travels, the number of lux dwindles as you back away from a light source, even though the source is still emitting the same amount of light in lumens. An area that is tilted away from a light sources also receives less illumination—which happens to be why the equatorial regions here on Earth are so much warmer than the chilly poles.\nBy the way, the purpose of the light sensor in your phone is to control the light level of the screen, adjusting accordingly to dim and bright environments. Inside the light sensor, a tiny semiconductor responds to incoming light by producing a small but measurable electrical current—a phenomenon known as the photoelectric effect. Similar sensors are used in some streetlights to turn them on when it gets dark outside.\nHere are a few of the many experiments you can do with your light sensor.\nExperiment with light from different sources (incandescent, compact fluorescent, and LED bulbs), or with light reflecting off of opaque surfaces and traveling through translucent and transparent materials.\nMultiple light sources shining on a single object will create multiple shadows—an umbra or total shadow where all the light is blocked, and a penumbra or partial shadow where one source is blocked and another source fills in. How do the light measurements in the various shadows compare?\nMake observations over a longer period of time: What happens if you record the natural light, either through a window or outdoors, in the same place at the same time every day? How does the light change over the course of an hour? A day? A week? A month? A year?\nFor maximum efficiency, solar panels must be tilted at an angle to maximize their illumination by the sun over the course of the day. Can you use the light sensor to determine exactly what this angle would be for your location? Would your result be different at a different time of year?\nIf your light meter is maxing out in full sun, try putting sunglasses or another light filter in front of the light meter.\nPut a single point source of light in a darkened room and measure the illumination at various distances from the light. (A candle makes a good point source, as does a Mini MagliteTM if you unscrew the cap so the small halogen bulb is exposed.) How does doubling or tripling the distance affect the measurement?Light obeys a mathematical relationship known as the inverse square law —as your distance from the source increases, the amount of light arriving at an area decreases in proportion to the square of the distance. Mathematically, the relationship is expressed as 1/r2, where r is the distance from the source. Not just light, but sound, gravity, electric force, and even spray paint obey the inverse square law. Do your measurements seem to confirm the law?", "domain": "optical_engineering"}

Before you opt for this correction program, however, it’s important to learn all there is to know about how it works.\nGentle Vision Shaping uses vision retainers to reshape the cornea and works to eliminate nearsightedness, farsightedness, and astigmatism. There is no surgery necessary in this regimen.\nWhat is Gentle Vision Shaping?\nGentle Vision Shaping is a vision correction program that works over time to correct patients’ vision. It’s easiest to think of it as the vision correction equivalent of braces.\nGentle Vision Shaping works by reshaping the cornea, or the outer part of your eye, while you sleep using a molding lens, or vision retainer.\nYou put the retainers on when you sleep at night, then remove them when you wake up.\nGentle Vision Shaping can correct both near and farsightedness, as well as astigmatism. Another name for this vision correction system is “ortho-k,” or orthokeratology.\nHow Does Gentle Vision Shaping Work?\nGentle Vision Shaping uses small retainers made of gas-permeable, hard plastic lenses.\nPutting them on is easy and requires little effort on the wearer’s part. To insert the retainer lenses, follow the steps below:\n- Apply a couple of drops of your insertion eye drops into the back of your lenses.\n- Place the retainer lens on your index finger.\n- Insert the retainer lens directly into the center of your eye in the face-down position.\nPractitioners recommend that you insert the right retainer lens first to avoid confusion.\nThe entire program takes approximately two years to complete, through which you need just two sets of retainer lenses.\nWho Developed Gentle Vision Shaping?\nGeorge Jessen developed the Gentle Vision Shaping system. Jessen began designing prototypes for the system in the 1960s using polymethyl methacrylate (PMMA).\nGeorge Jessen grew up with a father who was blind, which initially sparked his interest in preserving eye health.\nJessen started with corrective lens designs, dubbed “Orthofocus,” a type of gentle vision shaping lenses that were thought to operate more on luck than actual science.\nAs time progressed, his company was able to show that his product worked, but they had no scientific proof to back it up.\nBecause of this, the FDA did not approve this procedure until 2002.\nAre There Any Risks Associated with Gentle Vision Shaping?\nSome risks are associated with the Gentle Vision Shaping system, but they are similar to those associated with wearing soft contact lenses.\nOne of the most prominent risks of Gentle Vision Shaping is an increased chance of hypoxia. When the cornea experiences hypoxia, it may show signs of swelling and clouding. Hypoxia causes fluid to build up in the cornea, causing foggy or cloudy vision.\nHowever, the risk of experiencing hypoxia with Gentle Vision Shaping is low because the small retainers are used for shorter durations of time than other corrective lenses.\nAnother risk associated with Gentle Vision Shaping is a higher risk of eye infection, mainly bacterial keratitis. This can result in vision loss or blindness if not treated properly.\nWho is a Candidate for Gentle Vision Shaping?\nThere’s actually a surprisingly large number of candidates who qualify for Gentle Vision Shaping.\nThe procedure is FDA approved for all ages, but may be particularly interesting to those who meet any of the following conditions:\n- Nearsighted patients\n- Patients who are opposed to surgery\n- Those with a low or moderate astigmatism\n- Children who have experienced a drastic change in nearsightedness\n- Children with a family history of high or progressive nearsightedness\nThere are many qualifying factors for Gentle Vision Shaping, many of which pertain specifically to children.\nHow Much Does Gentle Vision Shaping Cost?\nDepending on how severe your vision issues are, the cost of Gentle Vision Shaping can range from $2100 to $3000. This estimate includes molds and retainers.\nInsurance does not cover Gentle Vision Shaping, but it does qualify for a Flexible Spending Account (FSA).\nDepending on the doctor you visit, you may also be able to use Care Credit to finance the cost.\nGentle Vision Shaping is an affordable permanent vision correction option, less than half the cost of LASIK and other vision correction surgeries.\nWhy Choose Gentle Vision Shaping Over Corrective Lenses?\nGentle Vision Shaping offers several advantages over traditional eyeglasses and contact lenses.\nThe Gentle Vision Shaping system was mainly invented to free patients from wearing corrective lenses throughout the day.\nGentle Vision Shaping is especially great for patients who work in dusty or dirty areas that could irritate their corrective lenses, as well as those who experience dry eyes.\nAnother great advantage of using Gentle Vision Shaping is that it has been proven to significantly slow the progression of nearsightedness.\nThis corrective method is a great option for young children experiencing nearsightedness, eliminating the worry of losing or damaging corrective lenses.", "domain": "optical_engineering"}

Here, we reported the first triplet-phosphorescence OSSL from nanowire microcavity of a sulfide-substituted difluoroboron compound. As compared with the un-substituted parent compound, the lone pair of electrons of sulfur substitution plus the intramolecular charge transfer interaction introduced by the nitro moiety lead to an highly efficient T1 (π,π*)←S1 (n,π*) ISC (ΦISC = 100%) and a moderate ΦP (10%). This, plus the optical feedback provided by nanowire Fabry-Perot microcavity, enables triplet-phosphorescence OSSL emission at 650 nm under pulsed excitation.

This treatment functions best on people with modest to high degrees of nearsightedness (nearsightedness), reduced to moderate levels of hyperopia (farsightedness) as well as astigmatism connected with myopia, and also that have thick corneas. It is the most well-known medical vision modification technique.\nPeople with normal eye view see objects plainly since images are brought right into a right centerpiece by the cornea and lens of the eye. Preferably, the cornea's curvature is evenly matched to its size in a typical eye. Individuals with astigmatism, myopia or hyperopia have actually off-and-on shaped corneas, so the things seen are not focused properly. LASIK adjustments corneal shape by accurate removal of corneal cells, and by doing so deals with the eyes' concentrating power.\nThere are, nonetheless, dangers to LASIK eye surgical treatment.\nThere is a remote chance of full loss of vision. If this occurs, it is usually due to the fact that the individual had a pre-existing condition which should have averted the surgical treatment to begin with, such as pregnancy, cataracts, arthritis, diabetes mellitus, glaucoma, or lupus. People with large students are additionally bad candidates for LASIK. Dry eye syndrome will certainly be intensified by this treatment.\nA couple of patients complain that they permanently see \"ghost\" pictures, have actually obscured vision, decreased comparison and poor evening vision. When LASIK wased initially introduced, 5% of people had post-operative problems; nonetheless, refinements in the treatment have created this rate to go down to much less compared to 1% if LASIK is done by knowledgeable experts as well as clients are correctly screened prior to surgical treatment. If troubles do take place, they could frequently be resoved by a retreatment.\nFDA has actually accepted LASIK laser eye surgical treatment because 1998. While there are a great deal of pleased people, there are nonetheless no long-term research studies concerning its effects. Understand the constraints and the risks of LASIK eye surgical treatment prior to you sigh for the treatment.\nThough much less well known, these little implants could enhance vision in people with moderate to modest myopia without the risk of irreversible eye damages inherent in the tissue elimination strategy of LASIK. Intacs are semi-circular disks dental implanted in the cornea which extend it to think a flatter form. Though somewhat much less specific compared to LASIK, they are removeable and also exchangeable, so if the person has an unanticipated over- or under-correction, the dental implant could be gotten rid of as well as one more of a different size inserted to obtain the desired adjustment. The implants are located at the edge of the cornea, so the central visual area is totally intact as well as undamaged, and the strength of the cornea is undiminished, making it a better alternative for pilots and also those that take part in call sporting activities where eye injury is a possibility.\nIntacs disagree for severe nearsightedness as well as greater than minor astigmatism (1.00 diopters), as the cornea could only be stretched up until now. If the Intacs are removed, vision go back to its preoperative degree. Besides vision adjustment, Intacs are likewise used to treat keratoconus.\nIntacs are FDA approved as well as One Decade research try this studies have disclosed no major troubles with Intacs as well as very few person problems; however, due to the fact that the procedure takes more training compared to LASIK, there are fewer eye surgery centers offering it. Nonetheless, the Intacs site offers a listing of specialists in each state, too a few in Canada, Europe and also description Mexico.\nSince many people do not wish to risk LASIK as well as Intacs can not assist those with extreme vision issues, intraocular lens implants (IOL) are a new choice approved by the FDA in 2004 to remedy modest to extreme nearsightedness. The Artisan lens, produced by Ophtec, is similar to the kind of lens implant used to recover vision complying with cataract eye surgical procedure.\nThe new IOL, called the Craftsmen, is intended for only people who have 2.5 diopters or much less of astigmatism.\nThe man-made lens does not replace the all-natural lens, but is placed in front of it. The major problem discovered with the dental implant was the steady loss of endothelial cells in the corneas of individuals that received the implants. The endothelium is a layer of cells that line the undersurface of the cornea as well as are essential in maintaining the cornea clear. A three-year research showed a regular steady loss of endothelial cells of 1.8 percent a year. At this moment, no person could predict whether this loss will continue at the very same rate indefinitely, and even its influence on corneal function.\nTo reduce lasting effects of the device on the corneal endothelium, the FDA is needing that the brand-new lenses be labelled to define that they should just be implanted in individuals whose corneal endothelial cells are thick enough to withstand small cell loss.\nA lot more major complications were couple of: retinal detachment (0.6%), cataract growth (0.6%), and corneal swelling (0.4%). The FDA is needing Ophtec to conduct a five-year follow-up survey of its dental implant people to much better assess the post-surgical incidence of cataract development, retinal detachment and other sensory illness.\nThe Craftsmen lens is meant to be an irreversible implant.Though it could be gotten rid of operatively, vision might not always return to what it was before obtaining the lens. Since it does not impact astigmatism, clients with this problem could still call for glasses.", "domain": "optical_engineering"}

Initial efforts produced 3D images engraved inside a solid piece of optically perfect laser crystal without damaging the crystal block surface.\nWhat is the difference between a Lead Crystal and an Optic Crystal?\nLead Crystal historically also known as flint glass due to the original silica source, contains a minimum of 24% lead oxide for color, clarity, sparkle and brilliance. Crystal can consist of up to 35% lead, at which point it has the most sparkle. The higher lead content also makes it much more difficult to form crystal during manufacturing. More lead content, the heavier the piece. The lead also make the crystal softer and more conducive to cutting. Swarovski crystal contains approximately 32% lead to maximize refraction.\nOptical Crystal is 100% Lead Free and extremely hard. Barium oxide is used principally in optical and crystal glass instead of lime or red lead. Glass, which contains barium, is lighter than lead crystal but gives comparable brilliance due to its high refractive index. Optical Crystal subjected to tremendous pressure to ensure no bubbles, flow lines or other distortions.\nCrystal without lead is not any less valuable than full lead crystal particularly when it is thick and heavy and finely designed. In fact, clear uncut crystal has to be particularly fine quality because the flaws can not be hidden by the cuts.\nHow to Display the Crystal\nThe best way to display your treasure is to place it over a bright light against a dark-colored background, for the following reasons. An image is formed from an engraved image in a crystal when light rays are reflected by the engraved points, which by striking our eyes make the regions with many engraved points appear white, while the regions with few points would let the light rays pass through and thus appear dark. If a light-colored background is placed behind an engraved image, those light rays that passed through the crystal body would be reflected by the background and strike our eyes; we in fact see the light-colored background through the crystal regions where there are few engrave points. Obviously the contrast of the image would be reduced under the circumstance.

The growth sectors of the World Outdoor Lighting Market are identified with precision for a better growth perspective.\nAccording to Market Research Future, the global outdoor lighting market has been segmented based on lighting type, distribution channel, application, and region.\nOutdoor lighting is a fixed artificial lighting that is used to brighten the outdoor areas. Outdoor lighting improves the visual performance to increase safety and security in outdoor areas. Demand for smart controls in street lighting systems and need for energy-efficient lighting systems for highways are expected to drive the outdoor lighting market during forecast period. However, the high installation cost of smart lighting is expected to restrain the market during forecast period.\nGlobal outdoor lighting market has been segmented into lighting type, distribution channel, application, and region.\nBy lighting type, the outdoor lighting market has been segmented into LED lamps, HID lamps, plasma lamps, and fluorescent lights. The HID lamps segment is expected to dominate the outdoor lighting market during the forecast period as they offer durability, high lumen output per watt, and are small in size. However, the LED lamps segment is expected to grow at faster rate during forecast period. HID lighting replaces the filament of a light bulb with the capsule of gas. HID lights require a ballast, which carefully controls the voltage supplied to the capsule of the gas. LED lamps provide better illumination than any other type of light. The demand for smart control in street lighting systems is expected to drive the LED lamps market during forecast period. In plasma lighting technology, light comes from a small and single point source. This light output is completely bidirectional and puts more lumens on the ground when it is needed. In August 2018, the European government launched Humble Lamppost project with an aim to save USD 2.46 billion on electricity every year. In this project, 60 to 90 million 25-year-old streetlights have been replaced with more efficient LEDs. This lamppost consists of smart lighting system, application-based wireless control, E-vehicle charging, push-to-talk system, and photovoltaic cells for lamp and mobile phones.\nOn the basis of the distribution channel, the outdoor lighting market has been segmented into retail and commercial. The commercial segment is expected to dominate the outdoor lighting market during the forecast period because outdoor lights are mainly sold in bulk, based on their companies, utility, or specialty distributors.\nBy application, the outdoor lighting market has been segmented into street lighting, highways, stadiums, parking lots, tunnel lights, parks, and others. The street lighting segment is expected to dominate the application segment due to various government initiatives taken for streetlight control systems. The highway segment is expected to grow at the higher rate during the forecast period.\nThe key players in the outdoor lighting market are Philips Lighting Holding B.V.(The Netherlands), General Electric Company (US), Osram Licht AG (Germany), Cree, Inc. (US), Eaton Corporation PLC (Ireland), Hubbell Incorporated (US), Dialight PLC (US), Zumtobel Group AG (Austria), Syska (India), Virtual Extension (Israel), Evluma (US) Halco Lighting Technologies (US), and Masco Corporation (US) among others.\nAbout Market Research Future:\nAt Market Research Future (MRFR), we enable our customers to unravel the complexity of various industries through our Cooked Research Reports (CRR), Half-Cooked Research Reports (HCRR), Raw Research Reports (3R), Continuous-Feed Research (CFR), and Market Research and Consulting Services.\nMarket Research Future\n+1 646 845 9312\nEmail: [email protected]", "domain": "optical_engineering"}

This cutting-edge approach has allowed them to bypass years of human labor and potential errors, leading to the optimization of these cells in just a matter of weeks.\nDr. Nastaran Meftahi, the lead author of the study and a researcher at RMIT University’s School of Science, highlighted that international teams have been in a race to develop perovskite solar cells that are not only cost-effective but also stable enough for long-term commercial use. Thanks to recent advancements, these cells have reached a level of stability where they can be considered for widespread deployment.\nPerovskite solar cells are particularly promising due to their potential to outperform traditional silicon-based solar cells in terms of efficiency and cost-effectiveness. However, the challenge lies in finding the optimal combination of materials and fabrication processes to maximize their performance.\nTo address this challenge, the researchers turned to AI. By training machine learning algorithms on vast amounts of data and simultaneously carrying out experimental work, they were able to rapidly identify the most efficient compositions and fabrication methods for perovskite solar cells. This process significantly accelerated the research and development cycle, which traditionally took years to achieve similar results.\nThe use of AI has enabled scientists to overcome human limitations and biases that often arise during optimization processes. It can quickly analyze and interpret vast amounts of data, identifying patterns and optimizing parameters that human researchers might overlook. As a result, the AI-generated solar cells exhibited improved efficiency and stability.\nThe team’s successful AI-driven approach demonstrates the enormous potential of this technology in accelerating scientific discoveries and technological advancements. It may also pave the way for further breakthroughs in other areas of research that require extensive optimization processes.\nThese findings bring us closer to the widespread adoption of perovskite solar cells in renewable energy systems, offering a viable alternative to traditional silicon-based technology. By streamlining the development process, AI could play a pivotal role in driving the transition towards cleaner and more sustainable energy sources.\nAs researchers worldwide continue to push the boundaries of AI-driven optimization, the potential for innovation in the field of solar cell technology is boundless. The next step will be to further refine the AI models and methods to continuously improve the performance and stability of perovskite solar cells, ultimately making them a commercially viable and scalable solution", "domain": "optical_engineering"}

By focusing a dual-color burst of laser light onto a fiber-optic cable, Raymer and doctoral student Hayden McGuinness were able to change the color of a single photon—a crucial step toward quantum computing.\nThe implications? If digital information can be stored and transmitted in a single electron and a single photon—rather than being stored in bits composed of many electrons and transmitted in light pulses containing many photons, as is currently the case—then quantum theory predicts a huge speedup of certain computer-intensive tasks, such as searching the Internet. Imagine “lightning-fast quantum Google,” said Raymer.\nRight: Graduate student Hayden McGuinness in the lab. Photos: Katie Campbell\nThe research by Raymer and McGuinness takes advantage of the fact that, at the level of single electrons and photons, quantum strangeness reigns. Think Einstein’s “spooky action at a distance,” the Heisenberg uncertainty principle and Schrödinger’s dead-or-alive cat (see sidebar). Because of this small-scale complexity, certain types of Internet transactions, such as searches, would become unthinkably fast and utterly hacker-proof.\nOne aspect of that quantum strangeness is wave-particle duality, which means that a photon of light possesses the properties of both a wave and a particle at the same time. This permits quantum bits to store values of both 0 and 1 simultaneously, unlike typical computer bits, which must have a value of either 0 or 1. This feature could not only significantly increase computational speed but could also render the quantum information safe from prying eyes. That’s because even the most careful observation of the quantum system would disturb its state, revealing the intrusion—another “spooky” effect.\nOne roadblock, however, is that quantum systems are based on the fact that electrons emit and absorb visible light. But existing fiber-optic cables are optimized to transmit infrared light. Raymer’s work potentially overcomes this obstacle.\nIn the next phase of their work, “the objective is to convert a single photon from the color that a common quantum memory will deal with into an infrared photon that communication fibers can transmit,” said Raymer, Knight Professor of Liberal Arts and Sciences. “At the other end, it has to be converted back into the original color to go into the receiving memory to be read properly.”\nRaymer, who is dedicated to making science accessible to nonscientists (see Science Literacy story), recently published The Silicon Web: Physics for the Internet Age (Taylor and Francis, 2009) for the curious nonscientist who has little or no mathematics or physics background. The book covers the basics of mechanics, electromagnetism, waves, optics and quantum physics as well as the science behind advanced technologies such as lasers, fiber-optic communication and semiconductors.\n“One can argue that scientific thought and methods have changed the course of human history as much as or more than anything else,” Raymer writes in the book’s preface. “To have a deeper understanding of where humanity is at present, it pays to study science and technology.”\n— Eric Tucker\nSidebar: Quantum Strangeness Reigns\n• Physicist Albert Einstein used the phrase “spooky action at a distance” to describe the quantum-mechanical phenomenon of quantum entanglement, in which the physical properties of two particles separated by vast distances remain strangely intertwined.\n• In 1935, physicist Erwin Schrödinger devised a deliberately absurd thought experiment to illustrate the strangeness of quantum entanglement. In it, an unfortunate cat, trapped inside a box with a vial of poison that is randomly released or not, is simultaneously dead and alive until someone opens the box and observes it. Similarly, in the UO experiment, under the action of the dual laser burst in an optical fiber, a single photon of light can end up being both red and green at the same time until someone observes it, at which time it must “decide” which color to be.\n• Formulated by physicist Werner Heisenberg in the 1920s, the quantum uncertainty principle states that the exact velocity and position of a subatomic particle can never be known simultaneously. For instance, measurement of the velocity of a particle will displace it by an unknown amount, invalidating the simultaneous measurement of its position. For light, measurement of the color of a photon will displace it in time by an unknown amount, invalidating the simultaneous measurement of its arrival time. Using this principle, it would be possible to tell whether or not an eavesdropper has tampered with the photon in an attempt to intercept a message being sent across the Internet.", "domain": "optical_engineering"}

While conventional sunglasses may protect the eyes from glare, they do a poor job of protecting your eyes from the industrial hazards of splashes, flying objects, and dust. In fact, conventional glasses can present their own hazards in the workplace.\n- It is a fact that the frame and lenses used in safety glasses are stronger than the frame and lenses used in conventional glasses. When an object strikes the lens of safety glasses it is very unlikely that the lens would dislodge. This is not true of conventional eye wear, especially those types with wire frames. When an object strikes the lens of conventional glasses, the lens can shatter, showering the wearer’s eye with shards of glass. This can happen, and it has happened. But, with a pair of approved safety glasses, the lens may break, but it will not shatter back into the eye.\n- Safety glasses also have shields to reduce the risk of foreign objects reaching the eye from the sides, top or bottom. Sunglasses do not.\n- Because sunglasses have a darkened lens, some people mistakenly believe these glasses will provide the needed protection when welding, brazing, or cutting. This is far from the truth. A darkened lens will not protect your eyes from the infrared (IR) and ultra-violet (UV) radiation. Wearing glasses with darkened lenses which are not made for industrial applications, can actually be more dangerous than wearing no glasses at all. For adequate protection from the visible light produced by welding, the lens must be of a specified shade. Sunglasses are not welding/cutting goggles.\n- What should you look for when selecting safety sunglasses? First, be sure the glasses are indeed safety eye wear, by checking to see if they comply with American National Standards Institute (ANSI) standards, the organization which sets the criteria for safety eye wear. This will be stated on the packaging and on the frame of the glasses. Look for “Z87.1.” This is the ANSI designation identifying the glasses as approved safety eye wear.\nAlthough not a necessity, consider glasses providing IR and UV protection. Look for glasses that are lightweight and adjustable. If the glasses don’t fit properly, they won’t be comfortable and thus they may not be worn. Try them on and adjust them before starting work. Get with your supervisor or safety tech if you are in need of a pair of safety sunglasses.\nPDF version is available through the link below.", "domain": "optical_engineering"}

Advances in LED lighting technology over the last decade have seen it become the dominant light source. Amongst other developments, this has led to extensive lighting research around the non-visual effects of LED light, and the potential for artificial lighting to disrupt and/or support human circadian rhythms.\nIt is understood that lighting conditions can affect visual performance, and in some cases, cause visual discomfort. The dominance of LED lighting has contributed to discussions relating to lighting metrics, colour rendering, and the spectral content of LED light sources. The possibility that exposure to light can have significant effects on human health and function beyond the obvious visual effect implies another basis for lighting recommendations. However, more knowledge is required before non-visual effects can be applied with confidence, particularly about the effects on healthy people exposed to light by day.\nLighting is vital in the modern world, enabling 24-hour society to exist. It is used for many different purposes, from enabling people to work accurately and safely, to visually enhancing our environment and improving accessibility and security.\nThe new edition of the Code considers the cost of lighting in relation to the health and wellbeing of an occupant and the environment. The recommendations included in the Code aim to strike a balance between the benefits and the costs. The basis of energy-efficient lighting is to provide the right amount of light, in the right place, at the right time, with the right lighting equipment.\nSplit over twenty chapters, the Code covers definitions for the various units of measurement and the interrelationships between them; calculation methodologies for a range of applications; photometric data; colour metrics; and maintenance factors for LED light sources and luminaires.\nMost lighting calculations are carried out using software tools based on the fundamental calculations that are listed within the Code for Lighting. The Code specifies the quantitative lighting requirements for a wide range of applications, along with guidance on how these might be achieved. By understanding these fundamentals, the designer, engineer, or facilities manager is equipped with the information they might need to verify automated calculations.\nThe Code sits alongside the SLL Lighting Handbook, which is more aligned to project-based lighting design, technology, and applications.\nProject manager and editor-in-chief:\n- Sophie Parry, CEng MIET FSLL, head of Akademie, Trilux UK\nChapter authors and principal contributors:\n- Allan Howard, BEng (Hons) FLIP FSLL, group technical director (lighting), WSP\n- Peter Raynham, CEng MSc MCIBSE FILP FSLL, professor of the lit environment, Institute for Environmental Design and Engineering, UCL\n- Sophie Parry (as above)\n- Peter Thorns, CEng BSc (Hons) FCIBSE FSLL, head of strategic lighting applications, Zumtobel Group Lighting\n- Ruth Kelly-Waskett, PhD CEng MCIBSE FSLL, senior associate, Hoare Lea, SLL past president\nContributors and reviewers\n- Steve Fotios, PhD CEng MEI MILP FSLL, professor of lighting and visual perception, University of Sheffield\n- Nigel Monaghan, FSLL, senior lighting consultant, Luminous Solutions\n- Peter Raynham (as above)\n- Peter Thorns (as above)\n- Technical secretary, SLL technical and publications committee\n- John Fitzpatrick\n- Ken Butcher, CIBSE Publications\nFor more information about the SLL Code for Lighting, visit https://www.cibse.org/knowledge-research/knowledge-portal/sll-code-for-lighting-2022\nFor more information about the Society of Light and Lighting (SLL), visit https://www.cibse.org/get-involved/societies/society-of-light-and-lighting-sll", "domain": "optical_engineering"}

It meant decades of work had paid off, and they will soon get one of the first chances to use the new cutting-edge technology.\nThe telescope is a joint project between NASA, the European Space Agency and the Canadian Space Agency, but much of the science work for two key pieces of the $10 billion spacecraft was done by Dr. Chris Willot and his colleagues at the Herzberg Astronomy and Astrophysics Research Centre in Saanich.\n”It’s been very exciting, but it was really nervy watching the beginning part of the launch,” said Willot. “At every stage, things seemed to be going well, so it was a relief for sure. The really great thing about this launch was the cameras on the rocket, which they don’t usually do … we got to actually see the telescope leaving [the rocket] and then a couple minutes later, the solar panel opened and we got to see it all deployed. That was really exciting to me.”\nWillot currently serves as the project scientist for Canada’s contribution to Webb, co-leading the team with principal investigator Dr. Rene Doyon with the Universite de Montreal.\nThe team provided expertise to the CSA, helping to guide the scientific goals of the telescope and designs of its fine guidance sensor, which allows the telescope to navigate, locate and lock-on to targets to observe, and the near-infrared imager and slitless spectrograph, one of four devices used to observe and study distant objects.\nWhile Willot joined the Webb team in 2006, the Herzberg centre has been involved since the very early stages of the project 25 years ago.\nIn addition to helping to guide the design and objectives for Webb, Willot said he and his team will also maintain Canada’s archive of all data collected by the telescope, helping to ensure it is accessible to scientists around the world, just as they have been doing for the Hubble Space Telescope since its launch in 1990.\nBut it’s the potential for future research once the telescope becomes operational in the summer that excites Willot the most, and scientists at the Herzberg centre will be among the first to use the telescope.\n“My own research area is in the very early universe, looking for the first galaxies,” he said. “I’m leading one of the two large Canadian projects … we know that galaxies early in the universe are quite different from the galaxies we see today, so we are trying to trace the whole evolution of galaxies.”\nWillot said Webb will be able to observe these distant objects in finer detail than previous space telescopes such as Hubble thanks to its larger size and its orbit further away from Earth’s surface.\n“With a mission like this, we will undoubtedly discover a lot of new things in the first few years which will challenge our understanding of the universe.”", "domain": "optical_engineering"}

Observing the Mediterranean while on board the ship, Raman wondered why the sea was so blue. The initial answer seemed to be that it was due to the scattering of light by water molecules, same as the explanation provided by Lord Rayleigh for why the sky is blue.\nTo test this explanation, Raman started experiments with his scientific collaborators and students at the Indian Association for the Cultivation of Science (IACS), Calcutta upon his return to India in September 1921. It soon became evident to them that the question was a fundamental scientific problem, and that the molecular scattering of light was a very general phenomenon which could be studied in gases and vapours, as also in liquids and solids.\nFor the next seven years, Raman and his associates continued to research this question, with many improvements to their scientific apparatus and techniques as they learnt more and more about the subject. In February 1928, Raman announced his findings to the press and sent his experimental data to Nature, where it was published in May 1928. The ‘Raman effect’ as it soon came to be called, was not only a phenomenon in itself, but one of the earliest proofs of the quantum nature of light. By 1929, the Raman effect was independently verified by other researchers, and in 1930 the Nobel followed.\nWhat is the Raman effect?\nThe Raman effect is the inelastic scattering of light by matter, meaning there is an exchange of energy between a photon of light and a molecule that it strikes. The molecule either gains (usually) or loses energy, so the scattered light has an energy different (usually lower) from the incident light. This changes the frequency and therefore the colour of the scattered light. The change of colour can act as an ‘optical fingerprint’ for the molecule.\nWhy does all this matter?\nThis discovery of an optical fingerprint of a material forms the core intellectual property for the field of Raman spectroscopy, which is a non-destructive, in situ method to analyse materials and live tissue. It has many applications that directly and indirectly improve the quality of our lives, including:\nChemistry – to identify molecules and study chemical bonding and intramolecular bonds.\nSolid-state physics – to characterise materials and measure temperature.\nBiology and medicine – for tissue imaging, wounds characterization and many other uses.\nBio-pharmaceuticals – to identify active pharmaceutical ingredients (APIs) and their polymorphic forms, if any.\nInvestigation of art and heritage works.\nAlmost 100 years after the original research, Raman spectroscopy remains a vibrant area. Over the years, over 25 variants of Raman spectroscopy have been developed, with new applications being found all the time. The global market for Raman spectroscopy is estimated to be $1.8 billion in 2021, with numerous companies all over the world making a range of products for the above applications.\nThe original research and intellectual property have been continuously expanded and improved upon by generations of researchers, engineers and entrepreneurs to create an entire industry. And it all began with one man’s curiosity about why the sea is blue.\nIn my upcoming course, Products, IP and Entrepreneurship, we will be exploring this journey of an idea, through its many stages of nurturing and support, the many challenges it faces along the way, to its final destination as a product and maybe an industry.\nRead more about the author of this post, Kiran HR, here.", "domain": "optical_engineering"}

Equipped with a high-brightness field emission gun (X-FEG) and a high-stability 300kV high-tension (HT) generator, the system easily facilitates the high-resolution, sub-nanometer scale imaging of frozen biological specimens. The electron optical column is equipped with ConstantPower™ lenses, which have optimized magnetic circuitry designed to reduce cross talk and keep beam hysteresis to a minimum. This platform is also equipped with an image corrector that removes the increased spherical aberration present due to the larger pole-piece gap of the C-TWIN objective lens, which is required to accommodate large angle specimen tilts in tomographic data acquisition. In addition, the system is equipped with a unique, one-of-a-kind cryogenically cooled sample handling and auto-loading system. The Titan Krios G2 platform has been configured with two detection cameras, a scintillated CMOS camera (FEI Ceta), which will be used for regular TEM/STEM imaging and diffraction applications and an energy-filtered Direct Electron Detection camera (Gatan K2 Summit on a GIF energy filter) for the low dose imaging of frozen biological specimens. In addition, the platform is equipped with two other capabilities, phase contrast imaging and STEM imaging. The phase contrast system almost entirely removes the necessity to acquire images of low contrast objects under beam defocus conditions. Finally, the STEM imaging functionality is essential in high-resolution studies of cellular macromolecules in situ.\n- Sample Auto-loading System - allows twelve independent samples to be loaded into a cassette, which can be transferred into the auto-loading system for delivery into the Titan Krios for imaging. The auto-loader is maintained at liquid nitrogen temperatures to protect the samples from any environmental factors, and each individual sample holder (AutoGrid) is robust and protects the sample against deformation and / or damage.\n- Ceta CMOS camera - The Ceta is a 16 Megapixel digital camera designed specifically for regular TEM/STEM imaging. The large field of view and small pixel size (a characteristic of CMOS sensors) allows a fast read-out for dynamic experiments and is capable, of recording full-frame 4k x 4k images at 30 fps and a reduced field of 512 x 512 at > 250 fps. The camera can also easily switch between this fast mode and high-resolution mode with ease.\n- Gatan K2 Summit Direct Electron Detector with GIF Energy Filter - The combined Gatan K2 Summit Direct Electron Detection camera and GIF energy filter – the “BioQuantum 967” allows for the direct detection of electrons at high sensitivity. In addition, the presence of the GIF energy filter allows the preferential detection of zero-loss electrons, thus serving as an additional mechanism to enhance the contrast of unstained, vitrified biological specimens.\n- Cs Aberation Corrector - The C-TWIN objective lens with its larger pole-piece gap is essential for high tilt angle tomographic acquisitions. Its symmetric design allows for the changing of the accelerating voltage without adjusting the stage z-position. Additionally, it ensures that there is no performance compromise, or any re-alignment between TEM and STEM imaging modes. However, whilst important for tomography, the larger pole-piece gap in the C-TWIN objective lens increases spherical aberration. The addition of an image corrector removes this added spherical aberration (Cs) thus restoring the TEM/STEM resolution to that of a Titan microscope platform with a smaller pole-piece separation.\n- Volta Phase Contrast System - A major issue in the imaging of unstained, vitrified samples is the lack of electron density, and thus contrast in the acquired images. A new, and cutting-edge approach that almost entirely removes the need for the addition of beam defocus is phase contrast imaging. By separating the phases of elastically and inelastically scattered electrons that pass through the sample by 90o, the in-focus contrast in the imaging plane can be drastically improved, which is beneficial in the imaging of weak phase objects, such as vitrified biological specimens.\n- STEM detector - The ability to scan the electron beam whilst acquiring the transmitted electron signal, a so-called “STEM” image is essential in high-resolution studies of cellular macromolecules. The incorporation of STEM functionality onto the Titan Krios G2 platform increases its versatility without compromising any of the other imaging modes of the microscope (TEM, EFTEM etc).", "domain": "optical_engineering"}

What a shame that such beauty is not real!” These beautiful verses by Lupercio de Argensola are usually quoted as an example of the baroque disappointment for nature’s makeups. It was certainly during the 17th century when the man discovered with astonishment the reason for the color of the sky, that up to then had been believed to be compact and immutable.\nThe color theory developed by Newton explains that white light is formed by the combination of all the colors of the rainbow.\nWhen we see an object of one color, it is because it reflects a certain wavelength and absorbs the rest, or which is the same thing, it reflects that color while absorbing the others.\nAt one end of the visible spectrum is red, whose wavelength is longer and therefore the lower frequency; because of this we call waves with a lower frequency “infrared”.\nAt the other end, violet, whose wavelength is shorter and therefore the highest frequency; therefore we call wavelengths with a higher frequency “ultraviolet”. But the sky, besides light composition, owes its color to another important factor: the atmosphere.\nIn effect, the light of the sun has to cross the atmosphere in order to reach us, and during that journey it looks altered. Minute particles of dust and water suspended in the air are smaller than the wavelengths of visible light, they do not have enough wave size to repel, but to divert slightly from its original path.\nThis is known as “dispersion”. And since the wavelengths on the blue end of the spectrum are shorter, they are dispersed to a greater degree than the rest of the colors, and this gives our sky its blue color.\nTo be exact, we need to add a third factor to determine why we see the sky as blue, and that is our own physiology. It happens so that, being consistent with what we have just said, the sky should be violet wavelengths as this color is still lower than in the blue.\nIf we see it violet is because our eyes capture the color in their own way, since they have cells sensible to only trhee colors: red, green and blue, and we perceive the rest of the colors by combination, that is, because they excite several of these three kinds of cells at the same time.\nTherefore, as our sight is more sensible to the colour blue than to violet, it is that colour we observe when gazing at the sky.", "domain": "optical_engineering"}

These magnetic clip-ons are cosmetic for your glasses and can be customized to your mood. Today, we are going to tell you the five advantages of having magnetic clip-on glasses.\nWhy Choose Magnetic Clip-On Glasses?\nAs mentioned, many people want to wear different glasses that compliment different occasions, but hoarding a large number of glasses is not the ideal solution. Magnetic clip-on glasses are detachable frames that connect to your glasses through magnets.\nThese robust magnets firmly hold the frame in its place and can be easily swapped out for a different frame. This feature can work well with sunglasses as well as prescription-based eyewear.\n1. Lens Leisure\nThe adaptability of magnetic clip-on glasses is one of its main features. Many people need prescription eyeglasses to correct vision problems but still desire the benefits of sunglasses.\nMagnetic clip-on frames solve this problem. These frames can securely retain prescription lenses while also allowing you to put an appealing shade on top when needed effortlessly.\nThis dual capability enables users to adjust to changing lighting situations and activities without changing glasses.\nFurthermore, the clip-on lenses are frequently made of polarized polycarbonate glass, which provides UV protection. These lenses are available in polarization levels ranging from UV 100 to UV 400, providing complete eye protection.\nNormal glasses go through occasional wear and tear and sometimes come apart in case of an accident. These shortcomings can prove harmful and cause serious damage.\nBecause they are composed of military-grade plastic like Trivex, that are used to develop shatterproof windshields. These frames and lenses are durable even under harsh conditions and can withstand extreme temperature with ease.\n3. Fashion Quotient\nMagnetic clip-on glasses are the latest fashion trend among the fashion-conscious. Their existence can be linked back to the 90s. With the recent revival of 90s fashion, clip-on glasses have made their comeback in the mainstream media.\nMany celebrities and public figures have been spotted wearing nostalgic clip-on glasses. The effortless ability of these spectacles to smoothly blend in any outfit while maintaining their unique voice has skyrocketed their sales.\nTo meet this need, various firms provide a variety of materials for the construction of these frameworks.\nFrom rich gold and silver embellishments to the futuristic appeal of aluminum and even denim injected with epoxy, these materials lend a touch of personality to your eyewear.\nMore importantly, these design and material innovations do not jeopardize the frames’ longevity, making them a functional but trendy alternative for anyone looking to express their individual style.\nBecause of their growing demand, magnetic clip-on glasses are readily available in the market. Many big firms retail clip-on glasses in their outlets and you can even browse their web portal for online shopping.\nThe worldwide eyewear market revenue has been projected to reach $141.5 billion by the end of 2023. This boom in sales has projected the global eyewear market to grow by 8.5% from 2023-2030.\n5. Certified Safe\nInitially, concerns arose regarding the safety of wearing magnetic clip-on glasses, particularly in relation to vision. However, extensive scientific research has provided conclusive data, establishing the safety of magnetic clip-on glasses.\nIn a recent study by Korean Physical Society members Dong Hyuk Kim and Hyun Mee Lee, contrast sensitivity between regular sunglasses and clip-on sunglasses was analyzed. The study found that the contrast sensitivity of the clip-on sunglasses was lower than that of the ordinary sunglasses with only one lens.\nThe contrast sensitivity at high illumination was higher as compared to low illumination. The contrast sensitivity of the clip-on glasses was better for a narrower lens spacing. Additionally, no difference in contrast sensitivity between the four colors coated on the mirror lens was observed.\nThe results have proved clip-on glasses to be just as safe for vision as traditional eyeglasses. Wearers can enjoy peace of mind, knowing that their eye health and vision are not compromised by opting for magnetic clip-on glasses.\n6. Savings Savvy\nMagnetic clip-on glasses are not only a style statement but also a financially groovy option. By opting for a magnetic clip-on glass, you refrain from purchasing multiple sets of glasses to change your style.\nThese glasses double down to act as your typical eyeglasses and can be transformed into funky sunglasses effortlessly.\nHaving this dual functionality assures that you get better value for your money and cuts down on your eyewear expenditure.\nFurthermore, magnetic clip-on glasses allow you to constantly upgrade your style statements and keep up with the changing fashion trends without additional expense. This functionality makes magnetic clip-on glasses a cost-effective and desirable option.\nCall it a style statement, an ode to the past, or a reasonable financial choice, magnetic clip-on glasses have succeeded in creating their niche audience.\nThe flexibility and durability of these glasses set them apart from their counterparts.", "domain": "optical_engineering"}
