Silicon has a low 2.329 g/cm3 density which is half the density of Germanium, making it ideal for weight-sensitive applications, such as silicon window. Silicon's price is much better compared with Germanium. Many military brand companies choose TC Optics Silicon lenses or windows.

Si Window Advanatages
With densities as low as 2.329 g / cm3, the si window is ideal for weight sensitive applications. In addition, compared with germanium and zinc selenide, silicon has less brittleness and higher thermal stability.
Birefringence will reduce the infrared imaging performance, so it is important to choose a material without birefringence. Because silicon has a cubic crystal structure, silicon windows do not exhibit birefringence.
