Hey everyone!
I buy storage units and recently got two leica dm750s from a unit auction. They're a little dusty but otherwise appear to work perfectly fine. I will be selling them eventually, but I'd like to play around a little and look at things like snail eggs from my aquarium. who knows, maybe I'll end up keeping one!
I've been a photographer all my life so I'm not unfamiliar with caring for optics, but I wanted to be sure I can treat these like normal glass. I don't know if maybe they have special coatings or something that is unique to microscopes. All the adjustments feel good. They're all smooth with no grit or sticking. The aperture(?) seems like it's a touch out of alignment on one, but I think it can be adjusted using two set screws?
Anything else I need to know, be careful of, check? I've ordered some slides and cover slips, so I'm looking forward to playing around with these a bit!
Leica DM750?

Hi,
In addition to the very useful links that Pau posted, you can have a look at the DM750 user manual for setting up the illumination: https://downloads.leica-microsystems.co ... ual_EN.pdf
When cleaning the optics (external surfaces only!), err on the side of caution. The lenses get easily damaged and because the lens diameters are small, individual scratches matter more than they would on a camera lens. Clean only as much as necessary.
Hopefully you'll keep at least one and get into microscopy
Regards, Ichty

thats what i was afraid of. theres only a little dust from storage so i think ill give a little hand blower a shot and see how it goes. i think its only the viewing lenses that are particularly dusty, im pretty certain the objectives are clean.Ichthyophthirius wrote:Hi,

For basic entry level stuff, are there any "must have" accessories? i think for now ill probably just be looking at gunk from my aquarium and dead skin etc. i seem to remember using dye in school to stain whatever was on the slide? also, apparently snail eggs are cool under a microscope, but i dont want to kill them by putting a coverslip over them. im assuming it is okay to have an uncovered slide on the platter so long as im careful about the objective crashing into it? i keep thinking these are silly questions with obvious answers but i want to double check as this isnt my realm and these scopes appear to be quite valuable according to ebay.
is it possible to look at minerals? i have some coal laying around, should i shave some dust onto a slide or is there another way?
i do think im going to keep one, at least for a little while! i may toss the other one up on here as i just noticed a sales section.

I expect you're looking at the "Equipment Exchange" forum. There are rules about no profit, so it's probably not the right place for your situation.freighttt wrote:i may toss the other one up on here as i just noticed a sales section.

Yes I actually just read the rules a few minutes ago, I'll refrain from posting it!rjlittlefield wrote:I expect you're looking at the "Equipment Exchange" forum.
