Germanium

Germanium

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.

Wavelength range of 2 – 16 µm rugged, durable material for defense, security and thermal imaging applications additional infrared lenses available in popular substrates.
