Silicon blank from ICC factory

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

Because of the low cost and density, the window sheet made of optical grade silicon has become a popular product for 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 its Knoop hardness is 1150. As a result, it is harder and less fragile than germanium.
