High Quality IR Germanium Infrared Lens (Ge Lens) in Swir
Description
Optical Ge window: Why use a Ge window?
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.
