Silicon

Optical Grade and Float Zone Silicon (Si):

Silicon is transparent from 1 µ – 7 µ; this makes it useful in IR systems. Silicon is mainly used in the 3-5 micron wavelength.

Silicon also has a very high refractive index and so significant Fresnel reflection losses can be expected unless some AR coating is applied. Antireflective coatings will also prevent scratching on Silicon substrates as Silicon is soft and easily marked.
