I managed to run across a neat old microscope for a pittance, planning to do some examination and perhaps photos of tool edges and a few other things. It's an Olympus Vanox AHMT or AH-BT2. This one is capable of reflected Brightfield, Darkfield, polarization and DIC illumination. Are there any fellow industrial/research microscope users around that have experience with one of these? I have a few questions about some of the techniques, prisms and filters and how they're used. Also could probably use some spare parts if anybody has any for these old scopes.
