Dielectric beamsplitter GCC-424 series

plate

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. •Material： BK7 fine annealed •Diameter Tolerance： +0/-0.2 •Thickness Tolerance： 3.5+/-0.1 •Incident Angle： 45° •Flatness： 5 fringes •Surface Quality： 60-40 scratch-dig •Parallelism： <3’
