  • Cheap Stereo Microscope DIY - SMD Work

    Finally, I found some time to come back to this project. As it turns out, getting the geometry right is difficult for wearer of glasses. The extension tube need to be shorter to compensate for the added distance between the eye and the ocular lens. The exact value doesn't really matter, just shorten the original 50mm by the approximate distance between your eyes and the outer surface of the glasses. Shortening it to 25mm did the trick for me.But it looks like that my eyes still have very uneven focus distances, even when compensated by the glasses. The mounting positions look very crooked not because I am unable to measure properly but to get the focus matching on both sides.I used a small mounting plate to screw on both sides of the cut middle part.

A layer of double sided tape help keeping the angle right. I didn't fixate the original side hinges, because they where very helpful when driving the holding screw into the mounting plate.Thank you very much for the inspiration to this project!

    The pictures are helpful, thank you! I think I know now why it works for you and not for me: I guess you are not wearing glasses? When I try your arrangement and without my glasses both pictures come together nicely. But with glasses on the eye distance is apparently too big and it doesn't work out anymore. My next try will be using shorter extension tubes.This should compensate for the increased distance between my eyes and the ocular. I will see (hopefully ;-)
