Solar Orbiter is a solar observation satellite launched by the European Space Agency from Cape Canaveral in 2020. Among the many complex instruments it carries are two imaging telescopes that have been designed to study the solar corona, operating in the extreme ultraviolet range. Using high precision optics, the mirrors are made by stacking reflective layers, which allows the selected wavelengths to be observed.
Franck Delmotte, a professor and researcher at the Charles Fabry Laboratory, leads the team that designed and manufactured these mirrors. He explains the stakes of this international project and the various steps involved in manufacturing the mirrors, from the polishing of the optical surfaces to the stacking of reflective layers through magnetron sputtering.
