Optical Solar Reflectors
Excelitas is a world leading manufacturer of radiation stable Optical Solar Reflectors for the space industry. An optical solar reflector (OSR) is used for the thermal control of spacecraft on the sun-facing sides of satellites by reflecting incoming solar radiation while simultaneously radiating internally-generated heat. Our OSRs are used in most major satellite programs for both civilian and military applications in Europe, USA and Japan
We are a highly specialized manufacturer of radiation stable micro-sheet coverglass with extensive on-orbit proven performance. With dedicated glass melting based in our UK operations and unique patented glass formulations, we offer a fully integrated high-volume manufacturing capability to meet your most challenging qualified-space glass requirements. Our advanced research and development continue to keep us on the leading edge of space technology.
我们将于1970年进入了太空业务，成为Pilkington Space技术。我们在Leo，Meo，Geo及更远的3000多种卫星上使用了我们独特的铈掺杂的微纸。
