摘要
Optical instruments are widely used in satellites for planetary and interplanetary missions where they are exposed to very high radiation levels. In this work a set of thin-film optical coatings, fabricated by Physical Vapor Deposition, have been exposed to high radiation dose in the CALLIOPE Co-60 radioisotope source at ENEA Casaccia Research Centre, in order to simulate the hostile radiation environment of interplanetary missions. Their optical behavior after irradiation has been analyzed.
