All 3 of the OCAMS cameras at the University of Arizona prior to launch.
The OSIRIS-REX Camera Suite (OCAMS) is a set of three cameras designed to image asteroid Bennu from different distances at different resolutions. PolyCam is a long-range camera designed to image the asteroid from a distances between 200—2 million km. MapCam provides high-resolution maps of the asteroid's surface, and SamCam documents the maneuvers and acquisition by the TAGSAM sampling system. All cameras use identical detector arrays but have focal lengths separated by a factor of 5. The detector is a 1024 x 1024 active pixel CCD array with 6.5 x 8.5 micron pixels.
