Special Features:

Anti-reflection coated for 3 um to 12 um; available in 4 sizes from 25.0 to 75.0 diameter; ideal for ir applications with its broad transmission range and opacity in the visible portion of the spectrum; germanium (ge) has high index of refraction, making it a perfect choice for applications that require low dispersion; germanium is also commonly used in imaging system operating; excellent for optics used in low power co; laser applications

Properties:

A color free item of transparent or translucent material, usually optical glass, having specific light dispersive and refractive properties. This item must have two plane-parallel surfaces and is designed for use in an optical instrument to provide a barrier to foreign matter and/or permit light transmission in or to the optical system.
