An optical solar reflector (OSR) is a component of a vehicle or machine designed to fly in outer space. The reflector consists of a top layer made out of quartz, over a reflecting layer made of metal. OSRs are used for radiators on spacecraft. The quartz outer layer lets the solar light through which reflects on the metal layer. This results in a low absorption coefficient. The quartz layer is a good IR emitter. The result of these properties is … WebApr 29, 2024 · Metamaterial Optical Solar Reflectors (meta-OSRs) are the first-surface coatings on the outside of a spacecraft, designed to effectively radiate infrared heat away … how to save numbers as text in excel
