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. Richard Gillilan MacCHESS
