Re: Microscope comparison SM-LUX-POL or American Optical (110?)

The microscope got here and on the exterior it looked fantastic. Unfortunately I will probably be returning it. The coarse adjustment gear is cracked and shorn and I am worried about some of the parts including lenses/optics. I have sent another offer to the seller at which point it would be worth m...

Re: Microscope comparison SM-LUX-POL or American Optical (110?)

Thanks much for the pointers!

I was originally looking for a BH/BH2 but they seem to pop up rately and cost nearly twice my budget.

I'm not sure what deep specimens means, all of my samples will be cut level to .03mm, a little different from biologic specimens I'm sure

Re: Microscope comparison SM-LUX-POL or American Optical (110?)

Thanks for the responses! I'm not super set on ebay but its definitely an option due to the buyer protection, i have experience refurbishing and repairing tools and some minor optics so as long as nothing is damaged im not too worried there. I however don't know which scope is actually better or if ...

Videos of rock specimens from the Black Canyon of the Gunnison

These are a few videos of rock specimens from the Black Canyon of the Gunnison. These rocks are metamorphic and nearly 2 billion years old. Unfortunately I was viewing these from a very strange scope they had in the visitors center and can't really ID anything from these videos. The changes in color...

Hey guys, I'm still trying to figure out what microscope I should go for, budget is around $1500 and it will be used for petrography/mineralogy at the hobbyist bordering on professional level. This is a .pdf that had some information regarding some used microscopes that are generally regarded as bei...

Re: Mineral thin section displaying Biotite

Roldorf, My first thin section took about 5 hours before I broke the glass and had to start over again, this was probably my 10th thin section and it took about 2 hours. First a rock is cut into a billet( approximately the size of the slide on the X/Y axis), afterwards it is trimmed on the Z axis to...

Re: Leitz SM-LUX-POL

Scarodactyl,

Thanks for replying!

I was under the impression that the stage on that SM-LUX-POL was both rotating w/ goniometer as well as having the X/Y stage, would only one be usable at a time? I have never seen such a thing in person.

Mineral thin section displaying Biotite

Hey guys, I know this forum isn't really geared toward mineralogy but I figured I would share!(please remove if it's now allowed) This is a .03mm section of rock that I ground down by hand, the picture was taken by holding my phone carefully over the monocular. One image is Plain Polarized Light, th...

Re: Leitz SM-LUX-POL

I would like to stay under $1500, the SM-LUX-POL's are definitely stretching my budget but I can make exceptions if absolutely necessary
