Re: LOMO microscope hunting for you

Possible errror correction and update. Reference is:- mikroscopfreunde-nordhessen.de/dateien/polam-311-ru.PDF So this refers to the P-311/312. It looks very similar to the 211, but has a lighting system mounted where the turret would be. There will be a lot of information on what the knobs & adjusti...

Re: LOMO microscope hunting for you

I have found this Lomo 213 manual on a German site. Reference to the site are on MicrobeHunter.
Polam-311-ru.PDF
I have downloaded a copy, but I do not know if copyright applies.
However, a search for the above should find it.
It seems comprehensive, but is in Russian cyrillic.

Re: Delaminated objective - how NOT to repair it!

Fluorite has "perfect" cleavage planes. Any form of pressure on the side of a crystal will make it part. The lenses are almost certainly made with the strongest face on the ground (concave or convex) surface. This would prevent the cleavage planes pulling apart. I have made a cabochon from fluorite,...

Re: Another Hello from England

Thanks for the very prompt reply. Nice slide pictures, which I had seen. This is some of the stuff I will be getting into. I have seen a picture of this 'scope. The later model has a turret and a different light source system underneath the body. Probably to achieve a longer/parallel light path. The...

Another Hello from England

I have several microscope, which are used on a local archeological dig, self funded, and recently took a turn towards the petrological microscope, with which I am having some difficulties. I decided to purchase a Lomo Polam P-211, lacking eyepieces & objectives etc. I am looking for a handbook, or a...
