Germaniumlens for thermal camera

Due to its high index of refraction, an anti-reflection coating is recommended on these ge windows for sufficient transmission. 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. High density (5.33 g/cm3) of germanium 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 Windows are available with three anti-reflection coating options, 3 - 5μm for mid-infrared applications, 3 - 12μm for broadband multispectral applications, and 8 - 12μm for thermal imaging applications.Germanium is an optical material completely impervious to ultraviolet and visible light, it is often used as camera lens for infrared thermal measurement.
