OPTICAL COMPONENT FOR PROTECTION AGAINST THERMAL RADIATION

摘要

The present invention relates to an optical component for a thermal screen intended to be placed between a cold medium and a hot medium. According to the invention, the optical component (6) includes a substrate (7) having a first surface designed to be arranged toward the hot medium, said substrate being made of a material transparent to optical radiation in the visible and/or near infrared range of wavelengths and said material having a crystalline or polycrystalline structure. According to the invention, the optical component (6) also includes a thin layer (8) deposited on said second surface of the substrate (7), said thin layer (8) being electrically conductive, transparent to optical radiation of visible and/or near infrared wavelength and reflecting thermal radiation of medium and far infrared wavelength.
