Re: Help me build an American Optical frankenscope

Transfer the head from #3 and the phase optics from #2 and put them on #6.... DONE! #6 has the coveted 5 place nose-piece AND great illuminator! Find a phase contrast intermediate/Bertrand tube for same = SUPER DONE!!

GUYS! I am humbled by your responses to my post... I have been, through no credit of my own, fortunate to learn from some mighty giants of microscopy and machining and hope to share more of those experiences

Re: Forgive me if I try to manipulate you, a little!!

Hi JeffO, these engravings are really nice! To me they look handmade by somebody who did this regularly. I know the Deckel engraving machines, but they were milling the material away. This looks as if cut with an engraving chisel to me. Have there ever been machines that worked with a pushed chisel...

Re: A hidden gem of superior optics - Wolfe/Kyowa

It was in good condition, except for two minor issues. The cross hair lens was originally glued and has come loose (any glue suggestions?) and the knob on the quarter turning filter beneath the stage is broken off. That broken off piece will be a pain to get out. Probably going to have to use a tin...

I've been looking for an excuse to try and mate my Canon DSLR with the big Zeiss surgical microscope Stemi 6S out in the machine shop - this may be a good time to see if I've got an adapter that'll do it. The Zeiss has a long working distance as well as a great depth of field for detail work. I keep...

That's very interesting, what does it use for the hydraulics, water, oil, air? It uses a clear oil that, to me, seems to be common mineral oil. The cylinders are sealed by black (I'm assuming) rubber O-rings so, the oil may not be petroleum based. This setup came from an estate so I'm also assuming...

In the setup pictured, the two images are slightly offset and converge in your brain, as a true ...

It's a microscope - I think they were intended for schools and designed to take the place of having to purchase separate stereo microscopes (which generally only magnify 60X at most) and compound microscopes (which, in an elementary school setting probably only go up to around 600X). I can't tell wh...

Because I apprenticed in machining at Carolina Biological Supply Co., Wolfe microscopes hold a dear spot in my heart.

It is a very, very early vertometer or, what today, we call a lensometer.
