Low Loss HR mirrors are essential in laser systems where the lowest possible losses are required.

Mirrors are manufactured using advanced beam sputtering technology. Low Loss HR mirrors provide maximum reflectance in a certain wavelength range and angles of incidence (AOI). Wide-angle (AOI 0-50°) mirrors are also available.

Ion beam sputtering (IBS) coatings are distinguished from other coating technologies by the possibility of reaching extremely high-quality specifications. IBS thin films feature higher density and durability compared to evaporated ones, making them resistant to environmental conditions such as heat, humidity and pressure. They also allow scattering to be minimized in dielectric layers which is usually a limiting factor for achieving high reflectivity.
