Infrared silicon windows: They offer excellent thermal conductivity, low density, high hardness, and excellent light transmittance in the 1-7μm range. Single-crystal silicon is commonly used in 3-5μm medium-wave infrared optical windows and optical filters or infrared temperature measurement lenses. It is also a common material for laser reflectors.
