More Fluorophors
The Dark Reader works with almost all your favorite dyes!
Dark Reader Technology can be used to detect many different fluorophors. In general, the ideal spectral characteristics for a `Dark Reader dye` are an excitation maximum between 420 - 500 nm and an emission maximum above about 520 nm.

It should be emphasized that the Dark Reader can also be effectively used to detect dyes that have maxima outside the above ranges. The only criterion is that at least a portion of the fluorescence excitation and emission fall within these ranges. Stated another way, the Dark Reader can be used to detect almost any dye excited in the visible range that does emit exclusively in the blue.

The table on the right lists a few commonly used dyes and their viewability using the Dark Reader. It should be noted that the listed qualifications are relative to an optimal excitation source and emission detector, such as a tunable fluorometer - not a transilluminator that can only provide excitation in the UV.
