Spectralon reflectance material is a perfectly diffuse reflecting material that is ideal for applications ranging from the UV-VIS to the NIR-MIR wavelength region. Spectralon is a highly lambertian, thermoplastic material that can be machined into a wide variety of shapes to suit any reflectance component requirement. Typical applications include back-light illuminators, lamp housings, integrating spheres, laser cavities and calibration targets. Three grades of Spectralon reflectance material are available for component fabrication. These include optical-grade, space-grade and laser-grade Spectralon.
