RLGM-1 Ring Laser Gyroscope Mirrors

RLG (Ring Laser Gyroscope) require mirrors and outcoupling coatings with very low absorption and scattering loss, high resistance to plasma environment and long durability. FOGphotonics provides such coatings done by Ion Beam Sputtering (IBS) with outstanding spectral performance and very low defect levels according to customer's specifications. IBS coatings find various applications where low loss and accurate performance is needed such as high finesse etalons.
