Germanium (Ge) lens
Germanium (Ge) is a crystalline material renowned for having the highest refractive index (4.0026 at 11µm) among commonly used infrared materials. This exceptional refractive index enables uncoated germanium to function as a natural 50% beamsplitter in the wavelength range of 2 to 14µm. Additionally, germanium exhibits remarkable hardness and density, making it an excellent choice as a substrate for infrared optical components that demand robustness in optical systems.
