Silicon Optics

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.

Edmund Optics features a wide variety of Silicon Optical Components, including optical lenses, optical filters, or windows. Silicon optical lenses are ideal for collimation or focusing applications that utilize monochromatic light. These lenses are available in a range of sizes or focal lengths for a wide variety of application needs. Silicon lens kits are also available. Silicon optical filters, which are integrated into IR applications such as FTIR spectroscopy, are used to transmit or block a specific range of IR wavelengths. Silicon windows are available uncoated or with a 3 - 5μm antireflection coating.
