I'm studying gemology on the side, and I find myself in need
of a inexpensive stereo microscope (is that an oxymoron?). So
far I have been able to borrow instruments when needed, but
this is getting a bit old. I'd like one for home.
A stereo microscope is necessary, as they present true erect
images and they allow you to perceive the depth of features
within stones. This is the only requirement.
The ideal scope would be a zoom scope that can zoom from 10X
to around 60X. It would include both overhead illumination and
provisions for darkfield illumination. Unfortunately, these
ideal scopes are very expensive from the only source I know of
yet: GIA's GEM Instruments - they have an ideal scope for the
incredibly low price of $2,795.
I would settle for a plain 10X/30X dual power scope. I have
catalogs from GEM Instruments, Edmund Scientific and Cole
Parmer. Cole offers dual power scopes for reasonable prices.
Of these 3, only GEM Instruments offers zoom scopes. If anybody
knows of other scientific supply companies worth checking out,
I would appreciate hearing about them.
I would *really* like a zoom scope, but it looks like I'd have
to go used (which is no problem for me). If anybody has any
suggestions where one might look for used scopes, I'd appreciate
hearing about them, too.
Thanks in advance for any and all suggestions and pointers. Please
e-mail - I'll post a summary if interest warrants.
