Darfield masks

#1 Post by imkap » Tue Jan 04, 2022 3:34 pm

I've just printed these, I don't know what are all of them for, the first row I understand as I have got a darkfield image with it. Others I don't :mrgreen: Are all of them for darkfield or something else?

The other filters are for oblique illumination https://www.olympus-lifescience.com/en/ ... iqueintro/ and Dodt contrast https://www.scientifica.uk.com/learning ... t-contrast.

Darkfield microscopy is great... I love it, I think I'll print some more sizes of the darkfield filters to match the magnification of the eyepieces. I have succeeded in illuminating with up to 40x objective, not sure is it possible with more?
