The 10GE20 is an uncoated, 25.4 mm in diameter and 2.0 mm thick Germanium window. Germanium has high index of refraction, making it a perfect choice for applications that require low dispersion. With its broad transmission range and opacity in the visible spectrum, Germanium is a popular choice for IR laser applications.
