Fluorescence Filters

Iridian offers excitation, dichroic, and emission fluorescence spectroscopy filters for confocal microscopy, flow cytometry, and other biomedical applications. These three different filter types are often used in a set in order to maximize the desired signal while minimizing the undesired signal.
