Product Desciption
AR/DLC coating Germanium windows
Germanium window is an optical window which is opaque to UV and visible light but has a broad transmission range in IR. It has minimal chromatic aberration due to low dispersion, and we recommend using an anti-reflection coating because of its high index of refraction (4.0 from 2 - 14μm).
Germanium (Ge) is a heavy, hard substance, with a Knoop Hardness of 780 - nearly twice that of MgF. It is often a good choice for applications where robust optics are key. It density is 5.33 g/cm3. Its transmission properties do decrease steeply as temperature increases, a property called thermal runaway, and we do not recommend its use for applications where temperature will routinely rise above 100 C.
It is well suited for IR laser applications, especially in situations where rugged optics are necessary. It can also act as a long pass filter, transmitting only wavelengths greater than 2 µm. Germanium is nonreactive to air, water, alkalis, and many acids, and highly scratch resistant.
