Product Description
General Introduction: Raytek monocrystalline silicon infrared filter is mainly used in laser, imaging, detection, temperature measurement, sensing, aerospace and other fields of sensor, so it is also called infrared sensor special filter.
Due to the good infrared spectrum characteristics and physical properties of single crystal silicon, the infrared sensor filter produced by Raytek mainly uses single crystal silicon as the substrate. By coating different refractive index and thickness of material film on the substrate alternately, the substrate has the functions of long-pass, short-pass, band-pass, antireflection, reflection and so on.
