An optical solar reflector (OSR) is a component of a vehicle or machine designed to

The quartz outer layer lets the

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 cold material.[1]

OSRs are often used in Geostationary orbits, where high radiation levels would cause other thermal surface coatings to rapidly degrade. This is due to the fact that the vast majority of geostationary orbits lie in the Van Allen Radiation Belt.[2]

Optical solar reflectors are a type of second surface mirror.
