New story today about a $1000 portable Raman device for counterfeit drug detection developed by the FDA. If this is suitable for field use in Africa for anti-malarials, I expect this could work for gemology in the field. Your tax dollars at work .
It looks like very nice product, photographing fluorescence reactions of materials illuminated with multiple wavelengths. Yes, it may have some really cool use in gemology, but it is not a Raman.
It's closer to deBeers DiamondView. But of does not use such short wave illumination. (Diamond View <230nm, very difficult and expensive illumination to produce)
anti Malarial drugs are very fluorescent. The original , quinine sulfate is used as a fluorescence standard for the testing of fluorescence spectrophotometers. Though largely replace by Rhodamine 6G in more recent history.
