Band Pass Filters

Our band pass filters have been especially designed as an excitation filter for several of our fluorescent probe classes, for researchers using broad wavelength excitation sources.  These band pass filters are ideal for use with broad wavelength xenon arc sources in standard fluorometers, to improve spectral isolation.  Our band pass filters are currently supplied as 1 inch rounds.


Ideal for excitation from 290-380 nm.
