Thanks everyone for the help. I was hoping it was something more exotic!

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...

Thanks all. Very helpful information!

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.

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...

Welcome engineer28. I am also i the process of setting up a Zeiss Standard for fluorescence. Hopefully, I will have some photos to post and we can compare notes along the way!

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...

Thank you both for the helpful advice. I have two filter cubes; I probably need to get them set up with appropriate excitation-emission ranges once I have the scope and illuminator working properly. It looks like this will be a long term project. The filters and blocks seem to be quite pricey, even ...

Nice photo. What was the host organism?

Beautiful collection of Zeiss microscopes!

Hello all, I am setting up a Zeiss Standard for epifluorescence using a Zeiss Standard and a mercury vapor lamp. There is a Blue filter slider in the epic-illuminator. The filter block has a mirror-like excitation filter, a dichroic mirror, and an orange colored emission filter. The slider above the...

Great Microscope. Congratulations!

All,

Thank you everyone for the rapid response. Just what I need to make a block. I'll post some photos once I get it done.

Thanks!

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...

Thanks everyone for all the help!

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.

IMG_0194.JPG I'm working on a send for my Zeiss Tessovar lens system. As you can see, it's a work in progress. I'm trying to figure out how to connect a digital camera to it. The instructions show a Zeiss film camera, but I need to connect a modern digital SLR to it. There must be a special adapter...

Thanks. I was able to get the old one out. Fortunately it's right-hand. You are right about the unusual threads- it's an uncommon thread pitch.

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...

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.

Welcome to the Forum!

Welcome to the forum!!!

Thanks, I'll watch for one of those cubes!

I have the section with the light, iris and slide-in filters. It's just off while I'm doing some maintenance. This is a Zeiss Photomicroscope. It's not currently operational, but getting closer every day. I found a Fl filter for it. There are a few others on EBay, but they want a fortune for them! I...

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.

Probably 4x would be fine. I'm looking for a Zeiss black enamel POL to match these though. I don't have a 1x on any of my microscopes. I don't know if I've ever seen one. I could probably use one. Most things I want to look at are in the low magnification range. When I'm outdoors, I carry a 4x and a...

Here is my Zeiss Standard Pol.
Objectives: 2.5x, 2.5x, 6.5x and 10x.
Adjustable analyzer, 1/4 lambda plate. LED light source.
Might be willing to trade one of the 2.5x's if anyone has something different...
