Silicon (Si) Windows manufactured from optical grade silicon are popular for the 1.2 - 7m spectral region due to their low cost and low density. Due to its low density (half that ofgermaniumorzinc selenide), silicon is ideal for weight sensitive applications, especially those in the 3 - 5um region. Density is 2.329 g/cm3and Knoop Hardness is 1150, making it harder and less brittle than germanium.
