Teledyne Technologies (NYSE: TDY) said its Space Imaging unit has surpassed 1,000 scientific imaging sensors in orbit following the Aug. 30 launch of NASA's Nancy Grace Roman Space Telescope aboard a SpaceX Falcon Heavy rocket from Kennedy Space Center in Florida.

The milestone includes sensors aboard the Hubble and James Webb space telescopes, in addition to those on the Roman mission. Teledyne supplied detector technologies for both of Roman's primary scientific instruments.

For Roman's Wide Field Instrument, Teledyne provided 18 H4RG-10 infrared detector arrays, each containing more than 16 million pixels in a 4096 × 4096 format. Together, the detectors form a mosaic of more than 300 million pixels, which the company claims is the largest infrared focal plane ever flown in space.

Teledyne also supplied three CCD311-20 detectors for Roman's Coronagraph Instrument, a high-contrast imaging system designed to suppress starlight and observe planetary systems directly.

In 2018, NASA awarded Teledyne a $23 million contract to provide 24 flight-quality sensor chip assemblies for the Roman mission. The contract was later expanded to 28 units. According to the company, each detector exceeded performance specifications and enabled a 20% increase in the instrument's spectral bandwidth.

"Reaching more than 1,000 scientific, space-qualified imaging sensors in orbit is a proud achievement for everyone at Teledyne," said Megan Tremer, President of Teledyne Space Imaging.

The Roman Space Telescope is designed to survey billions of galaxies and observe distant stellar explosions to support research into dark energy and the expansion of the Universe. The mission will also identify thousands of exoplanets and features a field of view approximately 200 times larger than that of the Hubble Space Telescope's infrared observations.
