Since the introduction of the first Ring Laser Gyroscope (RLG) by Mr. Kirkpatrick in the 70’s for inertial guidance systems in avionics there has been an increasing interest in high reflectivity mirrors with coatings with very low absorption and scattering loss, high resistance and long durability. Such coatings are deposited by Dual Ion Beam Sputtering (DIBS) with outstanding spectral performance and very low defect levels according to customer's specifications.

Elettrorava has recently delivered a new DIBS deposition machine and is preparing to complete the process set-up phase in close collaboration with the customer and under the scientific supervision and guidance of CNR-IMM Bologna. The ambitious goal is to repeatedly produce laser mirrors with a 99.98% reflectivity at 633nm for avionic applications.
