Condenser Zeiss achr apl 1.4

#1 Post by dtrinh » Thu Mar 02, 2023 9:40 pm

Hello,
Anyone interested in this conderser?
It has 7 positions in total, 2 of them are filled with phase contrast rings, 1 with iris diaphragm for bright field, 1 for dark field, so 3 are free for you to add other phase contrast rings.
This condenser is Achromatic and Aplanatic, meaning it produces light without chromatic and spherical abberations. Top quality I guess.
I have no suitable microscope to test it, but the phase contrast rings and the dark field stop look very good. The iris diaphragm can be open and closed normally. It would be better to oil it a bit though.

I'd be happy to swap something of similar value for it that you can use, assuming you're in the US (cheap postage). We do a kids' "Micronaut" program and it could upgrade one of our scopes.

Oh, well. Good thing is that your Zeiss condenser should be even more popular in Europe. Someone will have a good swap for you.
