Square and Rectangular Germanium Windows

Germanium (Ge) is an optic that is mainly used in Fiber Optic and Infrared applications (it is transparent in the IR range). Ge is often used for thermal imaging cameras working in the 8 to 14 micron wavelength, other common optical uses are for wide-angle camera lenses and microscopy. Ge has a high index of refraction and low optical dispersion. Please review our Ge properties page and advise if you would need info on our available AR coatings.
