Silicon Optical Components are used in a variety of infrared applications operating in the 1.2 - 7μm wavelength range, including NIR imaging or IR spectroscopy. Silicon's low density (2.329 g/cm3) is ideal for use in weight-sensitive applications. Silicon features a Knoop hardness of 1150, making Silicon Optical Components harder, less brittle alternatives to comparable Germanium Optical Components.
