ROBOPOL

RoboPol is a specialized photopolarimeter designed specifically for the 1.3m telescope at the Skinakas Observatory and commissioned in the spring of 2013. It was conceived, designed, and developed by the RoboPol Collaboration, and international collaboration including the University of Crete and the Foundation for Research and Technology - Hellas (FORTH) in Greece, the California Institute of Technology in the United States, the Max-Planck Institute for Radioastronomy in Bonn, Germany, the Nicolaus Copernicus University in Poland, and the Inter-University Centre for Astronomy and Astrophysics, in Pune, India. RoboPol was designed with high observing efficiency and automated operation as prime goals. It uses no moving parts other than the filter wheel. Instead, a combination of halfwave plates and Wollaston prisms are used to separate photons with orthogonal linear polarizations retard them, and simultaneously produce four images on the CCD detector for each source in the focal plane...
