Germanium is popular for its high index of refraction, broad transmission range, and rugged mechanical properties. With a transmission range of 2 - 16 μm and opacity in the visible portion of the spectrum, Germanium is well suited for infrared laser applications. However, Germanium is subject to thermal runaway, meaning that the transmission decreases as temperature increases; in fact, Germanium is nearly opaque at 100°C and completely non-transmissive at 200°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 is inert to air, water, alkalis, and acids (except nitric acid).
