Paper Abstract
We have built a new broad-band polarimeter (DIPOL-2), capable of measuring polarization with the precision at the 10-5
level. Two dichroic beam-splitters are used to split light into three passbands (BVR), simultaneously recorded with three
CCDs. A rotatable superachromatic λ/2 (or λ/4) plate is used as the polarization modulator and a plane parallel calcite
plate as the polarization analyzer. Simple yet effective design with small number of optical elements and moving
mechanical parts makes DIPOL-2 a highly versatile and reliable instrument with negligible instrumental polarization,
very well suitable for observations with remotely controlled telescopes. Current and planned observing programs are
briefly described.
