Optical solar reflectors
WebOptical Solar Reflector, a second surface mirror, is an important and crucial thermal control element used in spacecraft thermal management. These OSRs are bonded onto the radiator area of the spacecraft panel using an electrically conductive adhesive to provide a high performance radiating surface. Optical Solar Reflectors 57 113 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 …
