Product Description

General Introduction:
Germanium material has a high refractive index (about 4.0 at 2-14μm band), and can be coated to improve the transmittance of the corresponding band when used as window glass. Moreover, the transmission properties of germanium are extremely sensitive to temperature changes (the transmittance decreases with increasing temperature), so they can only be used below 100ºC. The density of germanium (5.33 g/cm3) should be considered in the design of a weight-critical system. Germanium Windows have a wide transmission range (2-16μm) and are opaque in the visible spectral range, making them particularly suitable for infrared laser applications. Germanium has a Knoop hardness of 780, about twice that of magnesium fluoride, making it suitable for IR applications in variable optics.

The Raytek germanium window is very suitable for infrared applications of various wavelengths, including in low power CO2 lasers. Germanium also has low dispersion and is an ideal choice for imaging applications. The window sheet is coated with antireflection film, which can provide high transmittance of 3 to 12 μM..
