About: Kepler photometer

An Entity of Type: agent, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

The Kepler photometer is the main instrument on NASA's Kepler space telescope. It is a Schmidt telescope (95 cm clear aperture, 140 cm mirror) with an array of 42 2200x1024 CCDs in the focal plane; each CCD is flat, but they are mounted on a curved structure to account for the curved focal plane. The CCDs are not abutting, so the focal plane is not entirely covered, but since the mission's goal is to observe a sample of stars, this doesn't matter.
