An American optical inspection station with a light table used by IBM. has both internal and external mirrors too to direct light on top of and underneath the item being magnified.
missing the light source, but, I don't see that as being a big deal as I can rig up something pretty easy with some white led's. It came with 10x eyepieces and has a zoom range of x0.7-4.2 so the resulting range is 7x-42x in (( STEREO ))
I picked it up at a local surplus shop. A little dusty, but the optics look clear. a few lights scratches on the light table surface. outdated for IBM I assume, but good enough for me!
the tape around the eyepieces was to just keep them from getting separated from the microscope while moving it around. I haven't cleaned it up yet, this is just how I got it.
I've tried to search the internet to see if i could find something like it, and though i easily found the optics on the internet, I haven't found the table anyplace. I wonder if it was some custom setup just for IBM. anyway, always wanted a stereo inspection station..
