Germanium is a high index material that is used to manufacture Attenuated Total reflection (ATR) prisms for spectroscopy. Its refractive index is such that germanium makes an effective natural 50% beamsplitter without the need for coatings.
Germanium (Ge) Optical Components are used in many Infrared (IR) applications or systems, including thermal imaging, spectroscopy, or with monochromatic light sources such as quantum cascade lasers. German (Ge) Optical Components are Optical Components designed for high performance in the Infrared (IR) spectrum without the use of Infrared (IR) anti-reflection coatings.
The Knoop Hardness of germanium (780) is approximately twice that of magnesium fluoride, making it ideal for infrared applications requiring rugged optics. Germanium is subject to thermal runaway, meaning that the transmission decreases as temperature increases. As such,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. Windows are typically availabe in a variety of sizes, contact us for availability.
