ZIMPOL/CHEOPS

ZIMPOL/CHEOPS(Zurich Imaging Polarimeter) is apolarimetricimager being developed for theVery Large Telescopefor the directdetectionofextra-solar planets.^[1]The imager is operated by theEuropean Southern ObservatoryonCerro Paranalin theAtacama Desertof northernChile.^[1]^[2]

It is also the imaging polarimeter subsystem of theVLT-SPHEREinstrument.^[3]

TheZurich 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 theVLT-SPHEREinstrument used at VLT's Unit Telescope 3, Melipal.

CHEOPS is anacronymforCHaracterizing Exo-planets by Opto-infrared Polarimetry and Spectroscopy.^[5]
