content: There are uncooled LWIR and SWIR cameras, as well as cooled LWIR, MWIR, and SWIR cameras. But I've never heard of an uncooled MWIR camera. They ALL seem to use a sterling mechanical cooler. Why is this? What is special about MWIR cameras that makes it so they can't be operated in an uncooled mode? And if it is actually possible, are you aware of any MWIR cameras that do so?

content: They were at least 4 microbolometer FPAs manufacturers that modified their products by changing the transmission window and offered them as MWIR/LWIR.There is just one but. The target temperature has to be above 100 degC if one wants to operate such camera solely as MWIR and get decent results. Not enough energy at room temperature in the MWIR band.Max

content: My question would be if your picture was realy coming from a MWIR system or a MWIR/LWIR one and what would be the result of comparison - in the same conditions - between MWIR and LWIR microbolometer uncooled camera when it comes to imaging a target having a temperature close to ambient, let's say a human body.Answering those questions would help to explain why there is plenty of LWIR uncooled systems and pratically no MWIR. The only situation where uncooled MWIR makes sense are high temperature scenarios.By the way, the Tachyon core mentioned before, in some datasheets there was a clear information about the minimum temperature of detection, given as 100 ºC.Max

The article says it could reduce the cost to about one thousandth of the current cost of SWIR cameras (those using InGaAs sensors). The company has raised 17 million dollars to start their operation.https://www.eenewsanalog.com/news/cmos-swir-camera-company-raises-17-million

content: Quote from: naze on June 11, 2019, 02:30:14 pmFiltered LWIR cameras are the sun-safe ones. Ones that do not have a long-pass filter can be damaged by the MWIR from the sun, because MWIR wavelengths pass through germanium lenses (though less then LWIR wavelengths do). The temperature of the surface of the sun is about 5500K, and at this temperature MWIR emissions are a couple orders of magnitude stronger than LWIR emissions (more than enough to not only pass through the germanium lens, but also damage the LWIR sensor).

content: I've been playing with a FLIR FC-309S security camera. Pretty easy to do basic (well, security...) stuff, but how close can this setup be made to be a general purpose IR camera? Somewhere deep in the configuration of the web interface they mention a Tau driver, so I assume it's a Tau core, but which Tau? The back of the core where the Tau-s I've seen have the USB connectors and such is taken by a custom board (with no visible USB socket). Then a few other questions bug me and googling or reading Flir's docs doesn't help much:Would it be possible to read temperature from this setup? It is not mentioned anywhere in the documentation or web interface, but must be possible...How do you access this thing programmatically? The docs mention things like: "Nexus SDK for comprehensive system control and integration", "Nexus CGI for http command interfaces", "Nexus XML-Based Control Interface", etc. I see the server taking commands like SERVERDeviceConfigGet, IRPolarityToggle&, IRNUCCalibrationStart&Calibration_type=1, but haven't found a complete list. The only reference to this Nexus stuff related to Flir is that apparently cameras like Flir A310 are also using it.Other than that I am pretty pleased that I can access from anywhere in the network, play with lenses, etc. Managed to put together an "IR microscope" or sorts, attached image is a overheating 0603 resistor.Appreciate your help...

content: Hi,I saw this for around £80 on eBay.It uses the Melexis MLX90640 so is limited to 32 x 24 real thermal pixels. Interpolation can easily quadruple the displayed resolution though.https://www.melexis.com/en/product/MLX90640/Far-Infrared-Thermal-Sensor-ArrayFor the money it is a neat little unit but it will be limited in what it can do in terms of thermography. It uses a very simple lens that is integrated into the MLX90640 and this does limit its range somewhat. NETD is 0.1K with an ROIC update rate of just 1Hz. I believe the MLX90640 refresh rate can be programmed to operate at up to 4Hz.This would make a reasonable educational tool to learn about thermal imaging, emissivity etc. I do have to question its long term usefulness however. It would be better to purchase one of the reasonably priced FLIR Lepton or Seek Thermal cameras IMHO. They have enough pixels to make them genuinely useful, rather than just a training aid. That said, if someone only has a limited budget, this might be worth buying to learn about the basics of thermography.Fraser

I'd be interested in peoples' thoughts on the merits of the Flir E8 XT versus the Testo 882. Both have the same resolution. I realise the E4 can be had for less and upgraded to the E8.Any other ones to consider? Fluke seem to be having range issues, so nothing available at a similar price point.

content: “I don't want to be scouring eBay, etc, for second hand Exx models.”A pity as that is the professionals choice and superior to the E8 XT and 882. I own two E40 unit’s that are running in E60+ configuration. Amazing value for money.If limiting yourself to just the E8 or 882 I would recommend the E8 model. I have owned a Testo camera and, whilst very well made I am aware that after sales service leaves much to be desired. I sold my Testo camera and it needed a calibration to remove 3 dead pixels. Testo apparently declined the request for a calibration and tried to sell the chap a used unit instead ! I would not want to own a Testo unit again for that reason alone. Good product support can be very important. FLIR use VOx microbolometers and Testo use A-Si microbolometers. I still prefer VOx based cameras. FLIR are a much larger player in the thermal camera market and there is a large user community in which to request help or advice. As Chanc3 has said, FLIR also offer a good choice of image analysis software, some free, some you have to buy. The Exx series really shines when used with ResearchIR 4 Max as that is a professional grade camera working with matched professional grade software. That being said, there are a great many contented Ex series owners, me included.Fraser

I'm not familiar with the previous range; was it E40, E50 & E60? How would you ensure a second hand one doesn't have problems with the sensor, or other? Can all the Ex0 series be upgraded to the E60?

However, in many instances their cameras are too expensive for what they give.Personally I would like one which the greatest details (thermal resolution) that my budget would allow and then additional features like video so that i can record the whole process or capture heat spikes and not wait until it happens and chance a capture via just camera. Finally I wouldn't mind one that has thermal data included so that i can analyse each its point later on.What other good priced cameras can you recommend? Around the $500 mark or lower. The more features the better.

Resolution isn't the most useful thing to have, focus control and a narrow fov can give more details. Radiometric capability are essential for any inspection beyond just identifying the location of an issue. In your price class you are very entry level. The fewest smartphone dongles will give you sufficient results. I honestly think the a used and modded FLIR Ex is a great starting point. It may not allow you to focus, but it gives you radiometric images and is calibrated.Let us know more.

Check composite video output is enabled in the GUI. Working on the electronics in these is challenging as they use very small components. Check for a water ingress damage as such is not uncommon, depending upon original deployment.Fraser

This used to work on some units.It almost sounds like the battery protection circuit is being activated and isolating the battery. If you can get some charge into the battery either via the power button hold down trick or by removing the battery and charging it externally you may recover the cameras normal operation.If you can send the camera back for a refund or exchange, I would do so, it sounds like a charge controller and battery protection issue. Such was common on the F1G2Fraser

I saw some other threads about hacking the HT units. Just wondered if there would be a way to adjust the lens to get a smaller FOV, or is it just what it is? Would also be nice to turn off the center crosshair, but I think that would involve hacking the software, if it's even possible. I'm not that savvy with all that stuff.

author: netchuck
author_rank: Newbie
timestamp: May 02, 2019, 03:51:44 pm
content: A NUC describes the per pixel corrections that are applied to make all of the pixels in the array appear uniform. For them to be uniform, they should all provide the same output value for the same scene.An FFC will create an offset map per pixel that makes each pixel have the same value, when looking at a Flat target.A two point NUC will also create a gain map per pixel to compensate for the different Gain that each pixel has, so that when looking at scenes with different levels, the pixels will still be uniform. This is typically done by using a “hot” and “cold” target.Sent from my iPhone using Tapatalk

content: NUC I think refers to compensating for differences in the physical array of sensors themselves. No manufacturing process is perfect.FFC I think refers to compensating for background gradient. The middle part of the convex focusing lens is thicker than the edge of the lens, so the middle part of the picture will have be more strongly effected by the IR emitted by the lens itself. This means that you need to subtract the background gradient caused by the lens to get a flat image, so that when looking at a surface with uniform temperature, the pixel values across the image will be uniform when that surface is imaged.

resolution vs FOV - Page 1

timestamp: May 04, 2019, 03:18:39 am
content: I'm looking for a thermal camera to take hiking to help me spot animals/wildlife for photography. I've tried a couple of the FLIR monoculars, which are nice, but I tend to close my left eye when using them, and it's just not comfortable after a while. I really prefer the smartphone-like devices where I can just look at a screen with both eyes. Anyway, this brings me to the question of resolution.Something like the Seek Reveal has a 206x156 sensor with a 36 degree FOV. Then there are higher res cameras like the Seek ShotPro with a 240x320 sensor. However, the FOV is around 57 degrees. This is fine for close objects, but even a deer that is farther away is going to look pretty small. What I'm wondering is, if I go to a higher res model, but the FOV is a lot wider, does that kind of negate the resolution?The Seek ShotPro seems nice, but I'm worried it might be fairly useless for my purposes. The Reveal XR is lower res, but has a 20 deg FOV, so objects will be larger.

author: CatalinaWOW

timestamp: May 04, 2019, 03:28:20 am
content: If you search around a bit you can find human factors studies which examine how many resolution elements on your object of interest are required for the basic goals of detection, classification, identification and so on. For game you certainly want fairly high up that scale. You want not only to be able to tell the cows from the deer, but want to be able to tell the bucks from the does.That usually requires something on the order of 20-30 pixels across the target, though you might get by with a little less or want a little more. Now you have to do the homework given the range at which you wish to observe your game, how big it is and so on to convert that to an angular size, and then into sensor coordinates. In a well designed system the FOV divided by the sensor dimension gives the sensor angular coordinates, but you need to verify that that is true for your camera.
