I am really appalled by this thread. In any specialty but pathology, a
physician would not be required to go to a camera store for his
optical equipment, or look through polarizing sun glasses at a
specimen. But it's what's out there - very few pathologists I work for
have polarizers on their microscopes.
A pathologist's microscope should have built-in polarization, and the
system should include a first order plate (full wave plate) for
determining the birefringence direction of crystals (needed for
identifying monosodium urate, a common diagnostic question).
When I was ten years old in 1949 I had a polarizer on my Dad's 1923
medical school monocular brass tube Leitz - I wish I had that scope
today (my sister has it, in a garage in L.A.) (I was an avid rockhound
- still am.) Why can't I have one 60 years later?
I don't mind buying my bone saws from Home Depot and my OptiVISION
magnifier from Amazon, but when it comes to my microscope I'd sort of
like to have the real thing.
