Metallic coatings are essential for numerous optical systems due to their high and
broadband reflectivity in the infrared spectral range. In contrast to well-established …

It has been known for some time that sputtered low-density coatings deposited under
vacuum (eg carbon or B4C), applied on top of high-density metallic coatings, can enhance …

This thesis presents the results of ray-tracing simulations of the mirror assembly of the
Athena X-ray telescope. It describes SPORT, the Silicon Pore Optics Ray-tracing Tool, and …

Recent progress in nanosatellite technologies allows to consider innovative new CubeSat
missions for scientific purposes. We present and evaluate the design of a small and cost …

High reflectivity grazing incidence mirrors of astronomical X-ray telescopes are usually
coated with thin layers of iridium, gold, or platinum. Due to a series of absorption edges …
