X-rays and extreme ultraviolet (EUV) light are emitted by excited particles in the solar corona because of its intense activity and extreme temperatures. Recent solar space telescopes in this spectral region showed increased performances thanks to the interference multilayer mirrors on-board. This thesis aims at enhancing such optical coatings, starting with an evaluation of EUV optical constant values available in the literature to select materials more accurately, and to refine optical simulations. This work allows us to introduce better simulations for an accurate calibration of the EUV Full Sun Imager aboard Solar Orbiter. Also, we show that mastering thin films deposition and optical and structural characterization techniques allowed u...
