Avantier offers a broad range of customizable germanium lenses, engineered for exceptional optical performance in demanding applications. These lenses are ideal for infrared (IR) and thermal imaging systems, featuring a high refractive index, low dispersion, and minimal chromatic aberration. Germanium’s rugged properties, including a Knoop hardness of 780 and a density of 5.33 g/cm³, make it suitable for weight-sensitive systems. Available in various shapes and sizes—spherical, plano-concave, p-convex, concave-convex, and aspheric—these lenses enhance the efficiency of optical systems using lasers, LEDs, analytical instruments, and advanced imaging technologies.
