Abstract

Optical coated elements are mainly optimized for their optical characteristics, such as transparency or reflectivity in a desired spectral region. However, for the space missions of the very next future it will be fundamental to ensure the sustainability of these optical elements at the harsh conditions of the relevant space environment, preventing the occurrence of any critical optical degradation of their performance. In fact, optical performance of the components strongly affects the data outcomes, and their degradation can lead to a misinterpretation of the scientific data due to an uncontrolled change of the instrument response; in a more dramatic scenario, the failure of a component can affect the operational capacity of the whole instrument. Electrons, protons and ions are considered among the principle causes of potential damage to optical coatings. Future space missions will operate in unexplored and hostile environments, facing new problems regarding the stability and validation of optical components, materials and coatings.

Goals

The clear definition of testing procedures to assess the robustness of optical components against the operational environment is pivotal to prevent in-flight failures and to fabricate robust coatings against radiation. The improved knowledge in the understanding the effects of electrons, protons and ions on coatings and the definition of tests procedure will be applied to develop and test optical components in view of their potential application to the ESA JUICE mission.
