Product classification
Infrared band pass optical filter
Infrared band pass filter mainly uses monocrystalline silicon as substrate. Germanium and zinc selenide films are alternately coated on the surface of the substrate, which are used in infrared sensor system. We can provide different bands of infrared band pass filter, the film layer of which has the advantages of high cutoff rate, high transmittance, solid film layer, good degree of finish, small absorption, stable and reliable performance, etc.
