What about this one?

Although the excitation is x-rays and not visible light, you are still
conceivably "identifying protein crystals with visible light". Seems to
mostly come from aromatics. Not sure how much damage you have to do to
get "enough" XEOL signal. Probably depends on how dark the room is.

My original question was:
Some years ago, I remember hearing about a microscope that used *visible* light
combined with some proprietary image processing algorithm to
distinguish between protein crystals, salt, and background. I can't remember
the company name or researchers involved.
Has anyone here heard of this?
None of the answers I received sound like what I remember. Nonetheless, there
are two companies that apparently offer visible-light technology for
recognizing crystals:
(a) Tritek: proteincrystalimaging.com/index.php
(b) Jan Scientific: (VISEX) see smb.slac.stanford.edu/news/Visex.pdf (their
listed products seem to be UV-based, but apparently this one is visible.)
Both of these are proprietary commercial products, so it is impossible to know
exactly what they are doing.
