Reflection and transmission properties of optical components can be selectively modified, enhanced or suppressed by applying specialized coatings to the optical surfaces. TYDEX offers a wide selection of optical coatings covering a wide spectral range starting from the deep ultraviolet (DUV, 200 nm) and extending to far infrared (FIR, 20 mm). TYDEX coatings are applied using resistant evaporation and electron beam (e-beam) deposition methods with machines such as the Balzers BAK-760 (Lichtenstein) and Izovac VU-2M (Belarus).
