SPHERE is an exo-solar planet imager, which goal is to detect giant exo-solar planets in the
vicinity of bright stars and to characterize them through spectroscopic and polarimetric
observations. It is a complete system with a core made of an extreme-Adaptive Optics (AO)
turbulence correction, pupil tracker and interferential coronagraphs. At its back end, a
differential dual imaging camera and an integral field spectrograph (IFS) work in the Near
Infrared (NIR) Y, J, H and Ks bands (0.95-2.32 μm) and a high resolution polarization …

The SPHERE is an exo-solar planet imager, which goal is to detect giant exo-solar planets
in the vicinity of bright stars and to characterize them through spectroscopic and polarimetric
observations. It is a complete system with a core made of an extreme-Adaptive Optics (AO)
wavefront correction, a pupil tracker and diffraction suppression through a variety of
