Silicon windows can be divided into two types: coated and uncoated. They are processed according to customer requirements and are suitable for use in the near-infrared band of 1.2-8μm. Because silicon materials have the characteristics of low density (its density is half of that of germanium materials or zinc selenide materials), they are particularly suitable for some weight-sensitive occasions, especially in the 3-5um band.
