GCC-424001 Dichroic Beamsplitter Plates
GCC-414 Dichroic Beamsplitter Plates
Dichroic Beamsplitter Plates allow NIR light to pass through and reflect visible light at 45 incident angle. They have a very steep transition between the region of transmission and reflection. They have a hard and dielectric coating using interference ranther than absorption to isolate the spectral bands. Unlike colored glass filters the cut-off wavelength will shift to shorter wavelengths with an increase in angle of incidence.
