Dielectric beamsplitter GCC-424 series

plate

Short-pass Dichroic Beamsplitters 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. Material：H-K9L AOI：45°
