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 … WebMaterials are desired that provide maximum specular reflectance of the solar resource at the wavelengths of interest (300-400 nm), which are optically durable (that is, they retain high performance for reasonable service lifetimes under outdoor environmental exposure), and which are low in cost.
