1. A visible light transillurninator system for viewing a pattern of fluorescence emitted by fluorophors capable of being excited by blue exciting light, and of producing light of an emitted type, wherein said emitted type is of a wavelength different from said blue exciting light, said system comprising:

  • a) a blue non-laser light source, with maximal output in the blue wavelength region housed within said transilluminator;

    b) a blue filter placed between said light source and said fluorophors and serving as a support for a material containing said fluorophors, which is capable of transmitting said exciting light from said light source and of preventing transmission of light from said light source in the wavelength range of said emitted type by said fluorophors; and

    c) an amber filter placed between said fluorophors and a light detector which is capable of transmitting light of said emitted type from said fluorophors and of preventing transmission of said exciting light from said light source;

    said system being constructed and arranged such that patterns of fluorescence emitted by said fluorophors are viewable.
