The lens with the red line is a 4x, the one with the blue line is a 40x the flat one is probably a 1x. To be honest they are a bit non-standard lenses that work well for general use. If you want more precise and better quality, I would replace them with a red 4x and a yellow 10x lens. If you want more powers, black is 20x and blue 40x. I did a video on replacing the lenses. ua-cam.com/video/WeLFAp2C4Lo/v-deo.html
It's manageable. You turn the knobs to focus then let it stabilize. With the remote you can start the video recording or take pictures without moving the microscope. Without the remote it be impossible to take stable pictures. If they made it with a metal base I would get that model instead, but seems they do not.
@@AlchemyWizard Thank you very much for the info. That's good to find out the real-world experience. Sounds doable. But I've just read a lot of reviews where people had problems focusing because the mount was so touchy. They would focus, wait for it to stop jiggling, and then try to focus again...sort of a Heisenberg uncertainty principle of focusing...you effect it just by touching it. Sometimes (they said) the ability of the knobs to make fine adjustments just wasn't there as well. I'd be glad of your opinion on the issue.
@@bradnelson3595 There are two ways to focus it, the one knob that raises and lowers the platform. That gets you close. then you turn the center tube part for the fine focus. but you do have to turn it a bit, then wait for it to stop shaking. Turn it a bit more. Then once you get it you snap the picture with the remote. That is how I am managing it. Would I like a metal or more stable base. I sure would, but I have not found anything like this video microscope that allows you to change the lenses. The other alternative is a trinocular microscope with a camera. Yep you are looking at over $800 dollars for the basic setup. More if you want like a 15mp camera. I am sure my next video microscope will be of better quality, once they make one.

@@AlchemyWizard What a great solution. If I buy this model, I'll definitely see about contacting you for the 3D printing files. I don't have a 3D printer but there are plenty of services online. I agree with you that it's a great microscope because it allows you to add your own quality lenses.
I think the Video quality and monitor quality is excellent. You can see the pictures I take of the colloidal with it. I've put some biological samples in there and about the only thing you may want with those is the stereo vision you only get with a microscope with binocular lenses.
does anybody know how to polarize the adsm249 digital microscope lenses? I know can cut the direct polarizing the adsm24? For the led lamp lights I can cut out circular small rings measured out with polarize film install them easily and turn them to deflect light, but as for the 3 lenses andonstar provides lens a d and the one mounted is there a glass lens I can buy to install on all 3 lenses so I can cut film for it that fits or an adapter? Does anybody know where they are or who sells the compatible glass lens?
I have no idea about that kind of modification, and I can't find polarized object lenses that you can purchase. I suspect cutting a piece of polarizing filter and sticking it inside one of the object lenses may work. I know some lenses will come apart. But you may consider just a polarizing filter for the ocular lens. Again you have to modify the microscope.
@@AlchemyWizard I 3d printed a universal cap lens last night that fits with an inner ring and teeth that snaps right on. It fits perfectly measured over the black cone that sticks out on lens A and D and another one measured that snaps right into those little square grooves on lens L along with the other 2. I just bought some tempered glass and high contrast linear adhesive film laser cut it and put it onto the glass. It works perfect now and spins fully to block out glare. I also laser cut film exact, used b7000 glue to mold onto my LED ring light. Its a project but worth it and makes a difference. I just don't know what kind of lenses these are they make in china on these newer microscopes. The older ones are flat and don't have that little black cone sticking out.
@@nikobobich9726 Great Job!!! Yes those pointy lenses are strange. I changed all mine out for standard ones. It added to the cost of the microscope, but the new lenses are a better quality over the stock ones.
@@nikobobich9726 Yes for the 249. I never replaced the single lens with another one. if that is what you're talking about with the two screws. I left the standard multiple lens adapter on and used standard microscope lenses. These are the lenses I replaced them with. They're not high end lenses. I tried a 4x and 10x high end lens and they worked poorly. It made the nanoparticle reflected light oval not round, high distortion. I'm guessing that it was something to do with the high end lens extra shaping lens built inside them and the frequency of the laser light. But these lower quality ones worked with almost no distortion, except on the very ends of the screen. • 4X Achromatic Objectives Lens: amzn.to/3D88jUb • 10x Achromatic Objectives Lens: amzn.to/3Dt0M2D • 20x Achromatic Objectives Lens: amzn.to/3FkActA • 40x Achromatic Objectives Lens: amzn.to/3f2qXDG
Great review! Gotta buy one! :) Thanks!
I'm glad it was helpful to you. The microscope has been incredibly helpful here with analyzing water samples and nanoparticles.
Hello Hermes! Did you ever figure out the f/stop of the lenses?
The lens with the red line is a 4x, the one with the blue line is a 40x the flat one is probably a 1x. To be honest they are a bit non-standard lenses that work well for general use. If you want more precise and better quality, I would replace them with a red 4x and a yellow 10x lens. If you want more powers, black is 20x and blue 40x.

Given the plastic stand, how much problem are you having with the stability of the scope?
It's manageable. You turn the knobs to focus then let it stabilize. With the remote you can start the video recording or take pictures without moving the microscope. Without the remote it be impossible to take stable pictures. If they made it with a metal base I would get that model instead, but seems they do not.
