Germanium Windows with DLC Coating

In the 2-12 μm range, germanium is the most commonly used material for making optical lenses and optical windows in high-efficiency infrared imaging systems. Due to its wide transmission range and visible light opacity, germanium is well suited for making optical components for infrared lasers and optical systems. Germanium's high refractive index and minimal surface curvature make it an ideal material for making low-power imaging systems. The small chromatic aberration often eliminates the need for calibration.  Learn More
