SAFARI imaging spectrometer
The SAFARI imaging spectrometer is the European ‘nerve center’ of Japanese infrared telescope SPICA (Space Infra-Red Telescope for Cosmology and Astrophysics telescope) and is being developed under the leadership of SRON Netherlands Institute for Space Research. SAFARI is an infrared camera with about 6,000 pixels that can make real ‘photos’ of the sky in three adjacent wavelength areas. Using a Fourier transform spectroscopy (FTS) detailed spectral information is obtained, allowing astronomers to determine the chemical composition of the observed celestial sources. TNO is developing the mechanism of this FTS.
==Extremely sensitive infrared detectors==
SRON’s leading role in the development of SAFARI is mainly due to the infrared detectors developed by SRON scientists. Extremely sensitive detectors must be used in SAFARI to gain maximum benefit from the low infrared emissions of SPICA’s cooled mirror. In June 2010, an international evaluation committee selected, out of four different technologies, the Transition Edge Sensor (TES) detectors from SRON together with the associated readout electronics.
