It is also the imaging polarimeter subsystem of the VLT-SPHERE instrument.[3]
The Zurich Imaging Polarimeter (ZIMPOL) provides diffraction limited classical imaging and differential polarimetric imaging (DPI) at 15 mas (milliarcsecond) resolution in the visible spectrum[4] and is one of three scientific subsystem integrated into the VLT-SPHERE instrument used at VLT's Unit Telescope 3, Melipal.
CHEOPS is an acronym for CHaracterizing Exo-planets by Opto-infrared Polarimetry and Spectroscopy.[5]
