Ge Windows and Lens

Lwir Ge Windows are ideal for IR applications at a long range of wavelengths, including use in lower power CO2 lasers. Germanium also has low dispersion, ideal for imaging applications. A Single Crystal Ir Germanium features a coating providing high transmission from 3 to 12 µm and 8-12μm.

·Ideal for near-IR applications

·Germanium With Dlc Coating and Broadband 3 to 12 µm, 8-12μm anti-reflection coating

·Ideal for applications requiring low dispersion

·Great for low power CO2 laser applications

Optical Windows are offered in a variety of substrates, such as Dlc Coating Silicon Windows, N-BK7(H-K9L), Ir Znse Windows. Multiple anti-reflection coating options are available for the Ultraviolet (UV), visible, or Infrared (IR).

Germanium (Ge) 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.
