Float-zone Silicon transmittance. Sample thickness 10mm.

Silicon is used as a high reflectivity mirror for lasers. Silicon is also used for windows and lenses in the 1mkm to 7mkm range. The refractive index is near 3.4 throughout the range. Silicon high thermal conductivity and low weight are attractive features in IR/FTIR applications .

Due to the strong absorbtion at 9mkm, Silicon is not suitable for use with CO2 lasers as a transmitting optic but is widely used for CO2 mirrors. The density of Silicon is only half that of Germanium and Zinc Selenide.
