497 DM Iridian Long Pass Filter for Fluorescence
Long Pass Filter for Fluorescence applications
Iridian DM series filters can be described as polarisation insensitive dichroic beamsplitters. They are typically used at angle of incidence of 45° ±1.5° to reflect (or transmit) excitation light to a sample, and transmit (or reflect) the emitted signal to a detector.
The DM filters have very high and flat reflection and transmission bands separated by a steep edge, making them ideal for applications that require beam splitting or wavelength separation.
