Abstract
The area of high precision solar spectropolarimetry has made great advances in recent years and the Zurich IMaging POLarimeter (ZIMPOL) systems have played a major role in that. ZIMPOL reaches a polarimetric accuracy of 10-5 by using fast (kHz) polarization modulation/demodulation of the light beam in combination with large-area array detectors. A new generation of improved cameras (ZIMPOL-3) are being implemented for the scientific observations at the solar observatory at Istituto Ricerche Solari Locarno. The new system is based on a flexible and compact modular design, which easily adapts to new applications. A faster electronics and new sensors with higher quantum efficency compared to the previous ZIMPOL versions, allow to achieve a better overall efficency. Future plans include observing campaigns at foremost large telescopes and the exploration of new technologies (e.g. CMOS).
