Re: как устроен механический тубус ortholux2 как можно перевести на бесконечную оптику,
I don't think it is possible to change a finite optics microscope to infinity-corrected. You would be better off getting higher-grade finite optics for your Ortholux 2. Main advantage of infinity systems is ability to insert additional attachments into infinity space. Being a beginner, it is not som...

Re: Where is Rafcamera?
This is sad - I found Raf through Ebay, and we designed an adapter for Olympus stereo microscope objectives to attach to Leica MS/MZ series microscopes - I use one of these adapters now.

It's a great microscope, it is fully compatible with Olympus UIS/UIS2 optics, so you can mount any infinity-corrected Olympus objective and any head from BX series, and enjoy the best image quality and ergonomics.

CORRECTION
I just had a few minutes to try the Meiji condenser on Olympus BX40 microscope - it will NOT focus on the field diaphragm opening!
Meiji condenser worked great (better than Olympus one) on finite Olympus scopes I tried it with before.
Just something to be aware off. Sorry for the confusion!

There are a lot of Nikon labophot 2 with an obsolete dead PSU. That unit looks like it could be used but I suspect from the asking price of a bulb it wouldn't be cost effective.

Re: Poor man’s Kohler illumination
I'm not sure that I am following you directly but Köhler illumination is simply a method of defocusing the illumination source at the field diaphragm plane. It has nothing to do with centering anything or providing limiting apertures anywhere in the system. Those are entirely separate controls one ...

A better-corrected condenser should help the color fringing you're seeing. As Phil suggests, the Olympus .90 swing-away condenser would be a good choice. The lack of contrast may be partly an issue of the objectives if they scatter light excessively. Are they Olympus Plan or UPlanFl and in good sha...
