\nThe Germanium (Ge) double-concave lens is an optical element with two inward-curved surfaces, typically made from high-purity germanium single crystal material. It is specifically designed for beam expansion, image reduction, and light projection applications. With a negative focal length, this lens effectively diverges parallel incident light. Germanium double-concave lenses are known for their excellent optical performance, including high optical transmission, low reflectivity, and strong chemical stability, making them highly suitable for infrared optical systems such as infrared imaging and spectrometer applications.<\/p>\n\n
