A dedicated instrument for the direct detection of planets, SPHERE, is composed of a polametric
camera in visible light, the Zurich IMager POLarimeter (ZIMPOL), and two near - infrared sub-systems: the Infra - Red Dual - beam Imager and Spectrograph (
IRDIS), a multi-purpose
camera for
imaging, polarimetry, and long - slit spectroscopy, and the integral field spectrograph (IFS), an integral field spectrograph.
We performed polarimetric
imaging of the RY ~ Lup disk with
IRDIS (at 1.6 microns), and obtained intensity images with the
IRDIS dual - band
imaging camera simultaneously with the IFS spectro - imager (0.9 - 1.3 microns).
