Far UV coatings for astrophysics and solar physics applications

Abstract

GOLD’s research is devoted to the development of novel coatings for the far (100-200 nm, FUV) and the extreme (40-100 nm, EUV) ultraviolet, and it is mostly focused on applications for space optics. Developments include high reflectance mirrors, narrowband coatings, filters, and polarizers. GOLD covers all stages from multilayer design and material optical characterization to multilayer deposition and FUV-EUV optical measurements. These stages are completed with the capacity to coat relatively large substrates in clean-room conditions to meet space requirements. GOLD has been involved on filters for WSO’s imaging instrument for over a decade. In the presentation, an overview of GOLD’s capacities to prepare and characterize FUV filters will be given, along with a summary of coatings that are relevant to space optics.
