More objective questions

IMG_0367.JPG Still trying to figure out my objectives. I think I'm getting closer! Here's one I just can't figure out... I have 2 Zeiss Plan 2.5 objectives. The first one is straightforward. it says "Plan 2,5/0.08" The second one is more complicated. It has a larger lens. It says "Plan 2,5/0.08" on...

OK, I have ended up with a bunch of different Zeiss objectives; all seem to be different styles. Some are all black, but some are half-black and silver. One is all silver with an "F". I'm not sure how to decipher the differences between these different series. Help appreciated!

Time to clean off the bench. Nice Zeiss Invertoskop project. Doesn't have any oculars nor any objectives. Everything here seems to be sound. For sale or trade.
Please PM me if you are interested.

Re: Zeiss Universal Questions

OK, I have the same microscope-- I just went to take a look. The "arm" in the binocular is not supposed to hang down. The side edge of it is barely visible in my scope. I don't want to take mine apart, but it appears one end has come loose on yours. The push-pull rod is not supposed to be bent. I ho...

Re: Zeiss photo support base

OK, Thanks. I think I get it. Loose connection without a rigid connection between the camera and the microscope. Now that I know what it is, I think I've seen it. It looks like the end of a soup can attached to the end of trinocular tube. It faces up into the recess of the support and acts as a ligh...

ALL, I am trying to build the system shown in the photo. The picture is from the internet. I just received the support arm for the camera, but I can't figure out how it connects to the trinocular tube. The manual mentions a "light-tight sleeve". I don't have one, I don't know what it looks like. I d...

Re: New Epi-Fluorescence

It looks like this will be a long term project. The filters and blocks seem to be quite pricey, even ...

Another Zeiss Tessovar Question

I hope someone knows the answer to this... The Tessovar manual shows several blocks (they look like wooden blocks) that are color coded to uses as stages for photography. Each one has a different thickness to correspond to the the 4 different lenses on the Tessovar. Does anyone have the measurements...

Re: Zeiss Tessovar

Thank you all for the assistance. I have found the M42 adapter and tubes on eBay. Just need to go camera shopping now.

I need to add a vertical focus adjustment on the stand. I can focus with the microscope stage adjustment, but I would like the option to move the lens up and down also.

Zeiss dovetails

I have several Zeiss microscopes. They came with a stripped out dovetail retaining pin. It's the little 5-part pin with a spring inside. They all look like someone wrenched on them with a pair of needle nose pliers. That's probably why the ended up getting sold on eBay. I don't know why they are alw...

Re: New user and beginner and zeiss microscope questions

Nice looking Zeiss! You can always add the trinocular tube later if you find you really need it. Might be a few hundred dollars to find a used one to fit the Zeiss.

Re: Which AO microscope with

I bought a AO100 in 1987 and used it for 30 years. I just sold it last month. It was still working fine when I sold it. It used infinity optics.
I sold it to a co-worker for $150 and threw in a dark field condenser.
