Slicer de pupille et de l'objectif complétant le spectrographe de l’instrument SPIRou
Installation of the pupil slicer and objective completing the SPIRou (InfraRed SpectroPolarimeter) instrument's spectrograph on the dedicated cryogenic bench, in the clean room. SPIRou consists of a near-infrared spectropolarimeter combined with a high-precision velocimeter. Installed at the Cassegrain focus of the Canada-France-Hawaii Telescope (CFHT) at the end of 2017, SPIRou was designed to detect habitable Earth-twin exoplanets in the planetary systems of red dwarf stars in the vicinity of the Sun. It could also unravel the mysteries of the birth of stars and planets, by observing for the first time the magnetic fields of protostars aged just a few hundred thousand years.
