Besides Ge Optical Round Window, other Infrared Window such as Zinc Selenide Windows, Caf2 Window, sapphire window and other Irregular Window are available upon request.
GE material feature high index of refraction (around 4.0 from 2 - 14μm), an anti-reflection coating is recommended on these germanium windows or Germanium Lens for sufficient transmission in the region of interest. Germanium is subject to thermal runaway, meaning that the transmission decreases as temperature increases. As such, these germanium windows or Germanium lens should be used at temperatures below 100°C. Germanium’s high density (5.33 g/cm3) should be considered when designing for weight-sensitive systems. The Knoop Hardness of germanium (780) is approximately twice that of magnesium fluoride, making it ideal for infrared applications requiring rugged optics. Germanium Infrared Lens, Germanium Aspheric Lens and other Germanium elements are available.
