Germanium (Ge) lenses are high-performance infrared optical components designed for MWIR (3–5 μm) and LWIR (8–12 μm) thermal imaging, spectroscopy, and laser systems. They offer exceptional infrared transmission, high refractive index, low dispersion, and good mechanical stability, making them the preferred material for precision IR optics.
