Description

Single Crystal Silicon Window Si Optical Window
Single-crystal silicon (SI) is a chemically inert material with good thermal conductivity, low density and high hardness, ranging from 1 to 7 μ M has good light transmittance. At the same time, it is in the far-infrared band 300-300 μ M also has good light transmission performance, which is not characteristic of other optical infrared materials. It is usually used for 3-5 μ M medium wave infrared optical window and optical filter substrate, due to its good thermal conductivity and low density, it is also a common material for making laser mirrors. The density of monocrystalline silicon is 2.316g/cm ³， Knoop hardness is 1150, which is harder and less fragile than germanium
