Description:
Silicon(Si) is commonly used as a substrate material of infrared reflectors and windows in the 1.5um-8um region.
The strong absorption band at 9um makes it unsuitable for CO2 laser transmission application but it is frequently used
for laser mirrors because of its high thermal conductivity and low density.Silicon is also a useful transmitter in 20um range.
