Helium Ion‐Induced Degradation Mechanisms in Optical Coatings for Space Applications

Advanced Optical Materials, EarlyView.
Although low‐energy helium ions represent a significant source of degradation for optical coatings operating in space environments, their effects remain poorly understood. Systematic irradiation of over 150 metal and dielectric thin‐film samples at 4, 16, and 100 keV investigates the damage mechanisms and their impact on optical performance ...
