Germanium is commonly used in IR imaging systems, covering the LWIR (8 to 12 µm) and MWIR (3 to 5 µm) wavelength range. One outside surfaces of Germanium windws are often AR coated with diamond (or hard carbon) producing an extremely tough front optics, and Germanium is more rugged than other IR materials, which makes it excellent as the protective windows for thermal imaging cameras.
