Low loss HR mirrors are also referred to as IBS mirror due to ion-beam coating technology. The mirrors provide maximum reflectance at certain wavelength range and certain angle of incidence (AOI).
IBS technology stands out by multiple advantages against other coating techniques. Due to fully automated control of deposition process coatings distinguish by high repeatability, sharper features, tighter tolerances. IBS thin films feature higher density, durability, high-damage-threshold, impenetrable to water vapor, which make them resistant to environmental conditions such as heat, humidity and pressure.
IBS coatings distinguish by nearly all specification being supreme to the ones provided by other coating technologies. It allows to minimize scatter in the dielectric layers which is limiting factor, then reflectivity higher than 99,9% is targeted.
Our selection of ion-beam sputtered coatings covers wavelength range of 343 - 1550 nm.
