Daheng New Epoch Technology, Inc. Dichroic Beamsplitter Plates GCC-414

Dichroic Beam splitter 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 rather 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.
