Teledyne said the launch of NASA's Nancy Grace Roman Space Telescope brought its number of scientific imaging sensors in space above 1,000. For Roman's Wide Field Instrument, Teledyne supplied 18 H4RG-10 infrared detector arrays that together form a focal plane of more than 300 million pixels. It also supplied three CCD311-20 detectors for the observatory's Coronagraph Instrument, which is intended as a technology demonstration for high-contrast imaging of planetary systems.
