Thanks for the file. I went ahead and had it translated to English. Polam-L.de.en.pdf I had previously found a document in Russian. lomo polam_compressed.pdf I was able to translate it into 'workable' English. lomo polam eng_compressed (1).pdf Just in case any of you are interested or other LOMO own...

SOLVED!!!! As I was taking the 2.5x objective to the retirement home, I decided to disassemble the entire microscope. Upon reassembly, I noticed threads on the bottom of the intermediate tube. Then the light bulb went off. This random glass piece that was in the box with the objectives that I could...

I'm starting to heavily lean toward putting the 2.5 back in the box!

And the POLAM!!!

Here are some views of the back of the objective And the condenser, both with the 0.85NA and without (for 0.30NA)

My wording wasn't the best there. I am able to remove the 0.85NA lens. There was no luck with focusing. Sorry for the confusion! I attempted to photograph the 'focused' image with the eyepiece removed on the 2.5x objective which shows most of the setup of the microscope: scope.jpg It is a normal nos...

Clutching at straws here but I wonder if the intermediate image is at a different height when using the 2.5x. If this was the case, what would need adjusted? I suspect maybe there is a missing element from the rear of the objective. back of 2.5 obj.jpg It seems to me like something is missing, but ...

The sanity check failed. Top/side lighting the slide and trying to focus, specifically at the 9mm mark was unsuccessful. Here is my auxiliary lens: aux lens.jpg Here are views showing the convex top and bottom: aux lens bottom convex.jpg aux lens top convex.jpg The auxiliary lens over light: aux len...

Thanks for all the replies. I will do my sanity check in a few hours when I get home :lol: . I tried manually holding the condenser and raising it up from the light source to the bottom of the stage, no luck. The auxiliary lens photo I posted was from the internet, not my actual lens. Mine is froste...

I hadn't tried that before. Unfortunately it still isn't focusing. I had tried to remove the 0.85 lens of the condenser with no luck. I placed the neutral density filter over the light output and it allowed me to see a blurred image, yet it still would not focus. I have a feeling it's something simp...

Thank you all very much for your replies. I'm sorry for not responding sooner, I was out of town and away from the microscope. I had seen that article before but am a little confused on what the 'ground glass condenser lens' exactly is with the Polam. Under the condenser set up is a swing out lens w...

Hello all, I am having trouble getting my LOMO 2.5x 0.05 objective to focus on a POLAM 213. The other objectives are fine with focusing, just the 2.5 I am having issues with. When I remove the ocular, I can see that the specimen is in focus, however when I add the ocular I cannot see the specimen. I...

Hello dmi3n, I was wondering if you or anybody else had a user manual for the Lomo Polam-213M?

Thanks in advance!
