Zeiss Jena Laboval ?3? I think, documentation for the Laboval series online starts and ends with the Laboval 4. By all accounts this is their upper mid range lab scope, with Amplival being the top of the line before you get to big scopes that have to be installed by a technician.

There's a large variety of Zeiss scopes that were manufacturered on this side of the iron curtain, as you can see this is an East German piece. Pretty good condition, scratchy condenser optics but the objectives and eyepiece seem to be in great nick, from a quick inspection, and that's what matters. Eyepieces are 10×'s, Objectives are a 3.2 semiplanar, a 10, a 40 planar (which I think will get a lot of use), and a 100 oil immersion. Pretty normal setup.

I don't have slides and slips yet so I can't do a proper mount, but this is pretty promising for just sliding a sheet of paper into the slide holder. Proper mounting will improve the focus plane immensely. 32× and 100× so far.

The illumination is off-centre and uneven but that's resolvable and anyway it might be fun to move to LED. I also want to build some top illumination brackets for opaque subjects.

I had like. A kiddies toy microscope growing up and I got as far as trying to make it do darkfield with pieces of cardboard, but never something this professional, binocular optics is such a big step up on its own.

The only real issue I've seen so far is that the stage Z axis is very sloppy, huge backlash. Everything has been stuffed with new grease recently so at least it moves smoothly, old scopes and old typewriters both have a tendency to seize if they're forgotten for more than a few months at a time.

I'll swing by the lake and pick up some algae and protist samples later, and I need to order slides and slips. Also I can print some darkfield and oblique illumination filters.

Probably not going to fuck too much with oil immersion, but who knows, also I'll keep an eye out for water immersion objectives.

I think that with an appropriate head replacement and some filter hacking I could get phase contrast microscopy up and running, probably scavenging some Amplival parts. I'd need to see. I can definitely get fluorescence microscopy working with an illumination upgrade. It would also be nice to gut the electronics and put in a simple battery powered illumination system I can charge over USB so I don't have to rely on wall power. Even the stock tungsten lighting is only 5W at 6V so that's easy to swing.

Objectives are DIN 45mm I think, and it sounds like many Eastern Bloc microscopes use standardized head mounts. I'll also be able to print a lot of parts for this, but I'll probably want to get some black filament for optical reasons.

First I want to do some protist sketches, I picked up a protists book at a used bookstore a while ago and it got me really hyped to do protist watching. This is definitely at some level me trying to replace macroscopic wildlife spotting in my life.
