grow Silicon material process optical Windows

Featured Product from Intrinsic Crystal Technology Co., Ltd. (ICC)


The transmittance ranges from 1.2 to 7 um.

Equipped with or without coated window patches and antireflective film window patches suitable for 3 - 5 um

Very suitable for weight sensitive applications

Because of the low cost and density, the silicon (Si) window sheet made of optical grade silicon has become a popular product in the 1.2 - 7 micron spectral range. Silicon is very low in density (half of germanium or zinc selenide), so it is very suitable for weight-sensitive applications, especially those in the range of 3-5 micron. Its density is 2.329 g/cm3 and Knoop hardness is 1150. As a result, it is harder and less fragile than germanium.
