Question: Has anyone used the 2000x magnification? How clear is the image?
Document: Good quality and certainly good enough for my needs. Clear image and smooth focus operation. The LED set up is very well done and effective. The only issue I have found, is that the image is not so great at maximum magnification. It may just be a dirty lens or it may be an optics flaw..not sure yet...whatever..hardly an issue considering the low price.-MarkkusUPDATE:The issue with maximum magnification was user error.
This replaces one eye piece toys and cheap camera microscope. Looking at an onion skin, on laptop, the images were clear. 2000x focus was impossible with onion skin. I hope there are uses for that magnification. I am complete novice with microscope, by the way. I reviewed the camera part of this microscope before I realized these were separated in the review part, but my review is for camera. Microscope controls are intuitive and feels precise.
Then, as I increased magnification more and more, I began to notice that focus was IMPOSSIBLE at 1000x or 2000x magnification. I tried slide after slide and to check the focus.
First: the highest magnification objective lens is oil immersion only. You must put a drop of oil on your slide cover and then lower the lens into the oil to focus on anything. You must NOT do that with the other three lenses.This is what allows the 2000x mag: light goes through oil instead of unsteady air. It's a fantastic feature at this price. Don't worry though, you can be happy just using the other 3 lenses, which is what I plan on using mostly.
I couldn't getthe microscope in focus for a clear image except the tiny central area, and although the illumination was fine for the 4x, 10x and 40x objectives,the light on the microscope was not bright enough for the 100x.The microscope does not provide rich color images as our other ones do. I will return this microscope.
This is perfect for the nerdy homebrewer like myself. The image is just as good as the microscope used at a local brewpub here (which is a heavy duty college type microscope).Only 2 very minor complaints:First, you have to assemble the microscope (which is simple) by attaching the top eyepiece section to the base but the hole for the thumb screw that you use to screw the two together was poorly drilled (but then it's an inexpensive microscope).
I also used the oil immersion system to magnify the bacterial smear that I have made at home (gram stained) and it was really awesome!I highly recommend this microscope to anyone who needs a microscope that can magnify the whole world under the objective.
I started taking Bio at my college and instantly became fascinated with the microscopic world. I wanted to have a microscope of my own and found this one to be extremely affordable. I wasn't expecting much based on what I payed, you know "you get what you pay for for." I was shocked when I started using it and realized it exceeded my expectations. It was better than the $2000+ microscopes I used at my school.Highly recommend to anyone looking for a good affordable microscope.
(8) Overall the view is sharp and clear at all magnifications using both eyepieces and all 4 objective lenses. (9) I haven't used the 100X oil immersion technique but my interpretation of this is to use oil on top of the slide 'slip-cover' to change refractive index of the glass slide and slip so that more of the object in view at 1000 or 2000X is in focus (allowing a much more 'flat-field' when observing your specimen.
They also last longer.So, how is this scope? Well it's better than what I used in high school and Chem I in university. It's way better than my 4 cheapie Tasco-style garage sale scopes and my homemade macrobellow system.Assembly was easy: loosen knob at top to remove top cover. Remove clear cap on underside of head unit. Place head unit on top of scope and re-tighten knob.
Answer: Not great to be honest, a little fuzzy and dim when used with wet prep slides or oil immersion.  It's as good as can be expected from a microscope of this price range though.
