Long Pass Filter for Fluorescence applications   

660 DM   

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.
