    I remember having problems with it in college, I could only ever see on one eye, no matter what I did on the microscope binoculars I could never merge those two circles into one.

    Now I bought myself a nice Bresser science TRM 301 microscope and am fiddling with the settings since two days and have finally ran out of ideas.

    Could it be that some people can not adjust the binoculars due to xyz? Or am I missing something?

    hi there

    since this is not electronics related, I have moved it to the off-topic members lounge area of the forum

    it is possible some one may be able to give you help .... I don't know if any of our members are opticians

    OK, thanks for moving, didn't know where it would fit best.

    Well, the theory is that you adjust the microscope until it works for you.

    I also have problems with binocular microscopes, and I have been known to just close one eye. Binocular microscopes are not stereoscopic so if you close one eye you don't lose information.

    Well yes, I tried adjusting it for the last couple of days, but it seems like an impossible task. I really wanted to get it working as it is intended.

    I suppose the question would be, if for some people like us the only way to watch through binoculars is with one eye?

    I have no problems with binoculars, but I do with binocular microscopes. I use neither regularly. It could be something about the way I hold my head. If you figure out what the solution is for you, let me know :)

    The Binoculars I have are 50x and at first were not centered yet both in focus. I noticed that I could gently twist the coaxial alignment to make it worse and better and even though it was fairly stiff and elastic, I was able to adjust it and stick to perfect alignment with a bit of twisting.

    Maybe get an optical microscope>composite video adaptor ?
    I've seen these advertised in the past but no idea who / where..
    Try e-bay / OLX etc.
    edit:
    Back again.
    Just Googled "Optical Microscope Adaptor"
    then added , Slovenia to the search.
    Try:
    (China) cn.microscope.com
    (Slovenia) micro-shop.zeiss.com
    otherwise google as I wrote above - lots of sites.

    Cheers Fuzz, that is actually what I have done. Problem solved. It really is worth the money. No strain on the eyes. I can really recommend everyone who has a microscope to do this. Your eyes will be grateful.

    although you lost stereo depth perception , at least you have better 2D vision. The unit has coaxial adjustment for this , did you try? unless it was a twist error.

    Oh, so that is what it is called? Yes, I did, unfortunately to no avail. I also worked in a lab for a short period of time, so I had quite a number of microscopes to test and play with and I could not, on any of them, see properly.

    if cylindrical correction is large in your prescription, this can cause distortion. but spherical coaxial and right eye offset spherical correction is std. Other issues like tunnel vision or glaucoma notwithstanding.

    If you work in a lab,you get an optical microscope composite video adaptor!
    If not,you get the council version.......A PATCH! :confused:
