Zeiss Opton Stativ W

#1 Post by Fen » Sun Sep 20, 2020 2:09 pm

Thought I share some (badly shot) pictures of my first microscope. It has sat in the basement storage of a lab since the 70's and with a big move they had to throw out a lot of old stuff, (and yeah, those olympus objectives were fished out of the dumpster)
So from the lab basement, it resided for years in my parents attic until I opened the case and fell in love with this goofy looking thing at first sight.

It has been a bit of a project to get it working properly again since it couldn't stay in focus, so I took it all apart, carefully cleaned it and applied some nye grease and is now fully working again. Lighting was a bit of an issue since since the only bulb it came with was blown and after seeing how difficult and expensive it is to get a new one, I bought a BA15D socket with a collar and after some modification it fits perfectly without modifying the lamp housing permanently.

Sadly the optovar polarization (I think?) lens is badly delaminated, so not sure if that is fixable. It works fine without it though and I'd love to score some more phase contrast objectives. I only have the 16x and 25x

On the right the old lamp and fitting. It sat inside a metal holder that was held in place with a spring. The new one on the left (Could only order per 4 on amazon) had the collar filed smaller and sits in front of the old holder. I'm still waiting for better bulbs that I ordered, but this'll do for now.

That Leitz looks like a diamond scribe? I wonder what that's used for.
The third is a Zeiss Jena 5177 4mm n.A 0.95 160mm. A bit of a weird one with a focus ring and doesn't work well with the others.

Congratulations. A nice microscope. I like the stage.

The Olympus DPlans are very good objectives. They will not be exactly parfocal with the Zeiss objectives so, it is more convenient to have a set of objectives from the same brand and line - if possible. Also, the Olympus and Zeiss objectives and eyepieces differ in optical corrections (chromatic aberration for example). This is mostly visible in photography.

Wonder what the shiny metal sub-stage assembly is - a special turret condenser ?

Thanks! Yes, it's a bit of a mixed bag, but for the money I didn't pay for it I'd say it was well worth the investment.
Under the stage is the condenser for phase contrast and bright-field. The knobs are for centering the rings. (2 for each)
Well.. one knob is missing. :cry:

Here is a nice article about this microscope I found.

I'm still trying to figure out a lot myself. :D

Lovely microscope!

I imagine you already have this brochure: http://www.science-info.net/docs/zeiss/ ... ochure.pdf
Zeiss Standard WL (somewhat fashion challenged) & Wild M8
Olympus E-P2 (Micro Four Thirds Camera)

Yep! Printed out and everything already. :D
Too bad I couldn't find the technical drawing anywhere, would have made made the disassembly a lot less nerve wrecking since I didn't know what to expect. Luckily all went well.
If anyone knows of its existence, I would love to have it.

Just got the camera adapter delivered today from china, so I fiddled around a bit with it. I borrowed my brothers Canon 600D, but since I have zero experience with DSLR's, i'll have to figure that out too.
Sadly I can't get it parfocal. The adapter can be extended to some degree, but not far enough. One option is to extend the phototube somehow, since lifting it a bit higher works fine. Sounds a bit like a hassle, so if putting something between the camera and adapter also works, I'd love to get some advise on that. I need to lift it 1cm or half an inch thereabouts.
