[en] In-flight recondensation of outgassing molecular species from a satellite platform or payloads could compromise the performance of onboard optical instruments. In our group, we investigate alternative ways to circumvent this issue through thermally functionalised optical surfaces. Micro-heating systems directly integrated within the surface of optical components offer the potential to increase power efficiency as well as heat transfer homogeneity in degassing molecular contaminations. The manufacturing processes of the heater have been initiated and precise models of such heating systems will be developed soon.
