Optical Solar Reflector (OSR), Microsheet (PDF, 0.12 MB)
JDSU microsheet optical solar reflectors provide low solar absorption and high thermal emittance to control satellite temperature. Developed by JDSU they have flown on many critical US satellites and numerous international satellites. JDSU offers Corning 0214 microsheet, which provides the greatest resistance to radiation-induced darkening and damage in hostile space environments. Silver is used as the primary coating because it provides optimum solar reflectance. Mirrors with low solar absorption, coupled with high thermal radiation properties, are used to reduce satellite operating temperature and diurnal temperature variations.
JDSU offers dielectric or conductive protective overcoats for solar reflects in addition to customized edge metallization.
