Large area CMOS image sensor specified to “help astronomers peer deep into the universe”.Teledyne Princeton Instruments has this week at SPIE Astronomical Telescopes + Instrumentation showcased its new Cosmos cameras.
The deeply-cooled COSMOS camera, supported by the next generation of Teledyne’s LACera™ (large area CMOS image sensor technology), is specified to “help astronomers peer deep into the universe,” stated the launch announcement.
The CMOS camera features an imaging area up to 81x81mm, back side illuminated technology, sub-electron read noise and >90% peak quantum efficiency.
It is specified for “cutting-edge astronomy applications such as low orbital object tracking, exoplanet characterization, and time-domain astronomy.”
‘Parallel readout architecture’
Jason McClure, chief technology officer of Princeton Instruments, commented, “CMOS designs have a parallel readout architecture for high-image rates. The charge-to-voltage conversion takes place at each individual pixel, allowing read-out nodes on every column of the sensor to operate simultaneously.”
Ravi Guntupalli, vice president and general manager of Teledyne Scientific Camera group, said, “The Cosmos camera with 66, 42, and 10-megapixels sensors will enable advances in astronomy, and open paths for further commercialization of large area CMOS by other industries. We’re excited to provide a powerful imaging solution that both drives innovation and expands exploration of our universe.”
Teledyne’s launch statement also notes that “as the market for space and ground-based astronomy technologies continues to grow, Teledyne is leveraging its advanced sensor and camera expertise to offer complete end-to-end solutions.”
“These solutions span from the James Webb infrared deep-field imaging telescope to the development of payload subsystems for communication satellites, to extremely broad-spectrum, and cooling technologies that enable deep space exploration.”
