No idea for solving the quiz but the stereo relief is extremely nice.

Are you aware of any sources, other than China, for adaptors ?
Rafael from Belarus makes very good stuff, but shipping in the current circumstances could be very slow

Re: Diatoms

...However generally I see the use of 2 polarisers being called "polarised light", I suppose it doesn't necessarily imply full XPL at maximum extinction. Just to clarify some concepts: - With just one polarizer you have polarized light. With two you can play with the angle of the analizer relative ...

Re: Diatoms

Weak polarisation but I can assure you that it's cross polarised. I suppose that's the partial cross polarisation you refer to? Yes, this seems what is called partially crossed pol. Crossed refers to the maximum extinction of light with no sample, period Parallel polarizers is at 90º of crossed, an...

Cross polarised, Dmap, 10x oly.
The image doesn't look cross pol at all, it seems like bright field, could you clarify your technique, please? (partial crossed pol, Xpol with 1/4 plate...)

Excellent slide and very well imaged, BTW

Re: Darkfield Adapter for Whole Slide Imaging

There are fiber optic light guides that end in a flat bar rather than a round point. I wonder if these would be flat enough to use on a setup like this. Time go I did some tests with my dual gosseneck FO guide and it was very difficult to set up but worked well enough to prove the idea. I saw those...

Re: Cube fluorescence for Zeiss IM

The double fluorescence cube is named "2Fl" and it's the same used in the Fluorocondenser IV for Standard and WL pictured in the linked auction.
I have several of them, but, sorry, all are in use. With a bit of patience it's not rare at ebay. The filters are 18mm and the dichroic BS 22mm

Re: Photomicrography set-up with DSLR...Charles Krebs

nigeldodd, The setup shown by Charles uses a special projective eyepiece (the Olympus NFK) deigned to do it. With a normal visual eyepiece you could also do the same just raising it few millimeters or (with low magnification objectives) just re-focusing the microscope. Not ideal but working well eno...
