Infrared Germanium Windows, inciuding LWIR Ge window, can be used in both mid-wave infrared (IR) and long wave IR systems, because, Germanium Windows have excellent transmission across 2-14 µm waveband. Every Single Crystal Ir Germanium is a widely used material for IR windows and lenses in thermal imaging systems.This high density window has a thermal escape which makes the transmission reduce as the temperature of the window increases. As such, these germanium windows should be used at temperatures below 100°C. Zoolied Germanium Windows are available off-the-shelf with three anti-reflection coating options: 3 - 5μm for mid-infrared applications, 3 - 12μm for broadband multispectral applications, or 8 - 12μm for thermal imaging applications. Due to its high index of refraction (around 4.0 from 2 - 14μm), an anti-reflection coating is recommended on these Germanium windows 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 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 magnesiμm fluoride, making it ideal for infrared applications requiring rugged optics. Zoolied Optical Windows are offered in a variety of substrates, such as Silicon Windows, N-BK7(H-K9L), Germanium With Dlc Coating, ZnSe Windows, and single Crystal Caf2 Windows. Multiple anti-reflection coating options are available for the Ultraviolet (UV), visible, or Infrared (IR).
