Effects of proton irradiation on thin-film materials for optical filters

Research output: Contribution to conferencePaper

Abstract

The behaviour of interference optical filters for space applications has been investigated under low energy proton irradiation. In order to understand the behaviour of the interference coating subjected to proton irradiation, the interaction of protons with coating and substrate was simulated by the SRIM code. A beam of protons of 60 KeV with an integrated fluence of 1013p+/cm2was used. The spectral transmittances of fused silica, TiO2and HfO2single layers and interference coatings were measured before and after irradiation and, according to simulations, no significant effects were detected in the visible-near infrared spectrum, while some variations appeared at shorter wavelengths.
