Germanium Wedge Window Lenses Germanium Wafer Optics

Germanium Wedge Window Lenses Germanium Wafer Optics


Germanium (Ge) Optical Components are used in many Infrared (IR) applications or systems, including thermal imaging, spectroscopy, or with monochromatic light sources such as quantum cascade lasers. German (Ge) Optical Components are Optical Components designed for high performance in the Infrared (IR) spectrum without the use of Infrared (IR) anti-reflection coatings. Germanium (Ge) Optical Components can range from Optical Lenses to Prisms or Optical Filters.

Germanium is subject to thermal runaway, meaning that the transmission decreases as temperature increases. As such, these germanium windows 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.
