Aerospace & Defense

We have over five decades of experience in designing and manufacturing advanced optoelectronic components and electronic assemblies for high reliability, mission-critical applications in Aerospace & Defense.


OSI Optoelectronics is a leading supplier of high reliability, radiation-hardened, space-qualified sun sensors worldwide.  Our devices have continuously operated in hundreds of spacecrafts for over 15 years.  Commercial satellites have incorporated our advanced photonics technologies for monitoring earth's weather and climate, high-speed free-space communication for offering data to most remote places on earth, and space sensors in navigation, communication, scientific instrumentation, matter analysis, and surface mapping.  These technologies enable sophisticated reconnaissance satellites and navigation satellite systems for national security.  Our optical sensors are used on unmanned spacecraft missions to other space objects for geo-mapping and manned spacecrafts traveling to and from earth's orbit.
