Paper Abstract
Since several years the Zurich Imaging polarimeter (ZIMPOL) system is successfully used as a high sensitivity
polarimeter. The polarimeter system, which is mainly based on a fast modulator and a special demodulating
camera with a masked CCD, has been continuously improved. The third version of the system (ZIMPOL-3) is
routinely used at IRSOL, Locarno. The fast modulation allows to “freeze” intensity variations due to seeing,
and to achieve a polarimetric sensitivity below 10-5 if the photon statistics is large enough. In October 2013
the ZIMPOL system has been brought and installed for the first time at the GREGOR telescope in Tenerife for
a spectropolarimetric observing campaign. There, the system configuration took advantage from the calibration
unit installed at the primary focus of the GREGOR telescope, while the analyzer was inserted in the optical
path just before the spectrograph slit after several folding mirrors. This setup has been tested successfully by
the authors for the first time in this occasion.
