Old Leitz HM-LUX (Info ? maintenance ? upgrade ?)

[ratapenado]

Hello,

I was offered an old microscope Leitz HM-LUX. I'm wandering if anyone has some info on it, and also what should I do to maintain and clean it (I see dust in or on the optics) and if there are interesting upgrades (especially for the lighting part).

Some details: I have 2 set of ocular lenses (x6.3 and x10), 4 objectives lenses (x4, x10, x40 and a oil x100). The lighting system is a small lightbulb in a tube with some kind of flatfield on top, and it's possible to make it move up and down. I don't think it's a condenser and there is no diaphragm. The light intensity is also controlled by the electric box (several intensities are available)


I'm adding some pictures.

Thank you in advance
