Commercial optical coatings in space

Abstract The use of commercial optical coatings for space applications the aptly named “New Space” missions is a state-of-the-art trend. These products are generally less costly and time-consuming in their production therefore, there much wider range available compared to custom-made products. However, reliability manufacturing processes key concern. Additionally, resistance against environmental degradation mechanism at operating temperatures needs be evaluated. In this study, seven with multi-layer thin film consisting filters, mirrors windows have been selected from various manufacturers results regards process verification exposure testing presented. impact effects on performance evaluated, particular emphasis cryogenic temperature. Finally, guidelines precautions applications.
