Optical solar reflector
 | This article needs additional citations for verification. (January 2017) |
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 a good emitting, low absorbing material, thus making it a .[1]
Optical solar reflectors are a type of second surface mirror.
