Silicon wafer
Silicon single crystal is usually used as the substrate of 3-5μm mid-wave infrared optical window and optical filter. It is a common material for making laser mirror, infrared temperature measurement and infrared optical lens because of its good thermal conductivity and low density.
Applications :
Because of its good thermal conductivity and low density, silicon is a commonly used material for laser reflector, infrared temperature measurement and infrared optical lens.In addition, silicon is often used as a window for infrared detectors.
Product Advantage :
More than ten years of processing coating experience, stable quality
Independent production line processing, batch can be customized
Material growth – cutting – polishing – coating – full coverage
Delivery date, quality and price are controllable
