Patent ID: 6914250

Claim:
A visible light photoluminescent imaging system for viewing one or more patterns of fluorescence emitted by fluorophors capable of being excited by light of an excitation type and capable of emitting light of an emitted type, said system comprising: a) an electroluminescent light-producing element having a luminous surface that produces light; b) a first optical filter positioned between said the luminous surface of the electroluminescent light-producing element and said fluorophors, wherein the first optical filter is capable of transmitting light of said excitation type and of substantially preventing transmission of light of said emitted type; and c) a second optical filter positioned in optical communication with said fluorophors, wherein said second optical filter is capable of transmitting light of said emitted type from said fluorophors and of substantially preventing transmission of said excitation light; said system being constructed and arranged such that patterns of emission from the fluorophors are viewable.
