Germanium is an optical material with a diamond-like crystalline structure, typically used for creating high-quality optical components such as lenses, windows, and substrates. Germanium’s high refractive index and transparency in the infrared region make it a preferred material for infrared optics, including thermal imaging systems, spectroscopy, and other applications requiring precision and durability in challenging conditions. We offer Germanium in various thicknesses and in both uncoated and coated, including AR/DLC (Amorphous Diamond-Like Carbon) and AR/AR Coatings.
