Abstract
A system for coating a substrate with a thin film which has a high transmissivity in the visible spectrum and a high reflectivity in the thermal radiation spectrum. The film coating has at least one carbon layer crystallized with a diamond structure and doped with foreign atoms, the carbon layer being electrically conductive depending upon the doping concentration cA of the foreign atoms and having low radiation emissivity in the thermal radiation spectrum.
