Ge Windows and Lens

Because Single Crystal Ir Germanium broad transmission range (2.0 - 16 µm) and opacity in the visible portion of the spectrum,Lwir Ge Windows is well suited for IR laser applications. This makes it an ideal choice for biomedical and military imaging applications. In addition, LWIR Ge windows is inert to air, water, alkalis, and acids (except nitric acid). Germanium's transmission properties are highly temperature sensitive; in fact, the absorption becomes so large that germanium is nearly opaque at 100 °C and completely non-transmissive at 200 °C. Ge has an index of refraction of 4.004 at 10.6 µm.

Zoolied Optical Windows should be selected based on the material transmission or mechanical properties of the substrate. Optical Windows do not cause change in the magnification of a system. Zoolied’s Optical Windows are offered in a variety of substrates, such as Silicon Windows, N-BK7(H-K9L), Germanium With Dlc Coating, Ir Znse Windows, and Crystal Caf2 Windows. Multiple anti-reflection coating options are available for the Ultraviolet (UV), visible, or Infrared (IR).
