DIPol-UF: Three-band high-speed polarimeter
The new, high-precision astronomical imaging polarimeter DIPol-UF
(Double Image Polarimeter – Ultra Fast) was built by the research
group from the University of Turku (UTU), Finland, in collaboration
with the Leibniz-Institut for Solar Physics (KIS), Germany; see the
Nov 2020 publication by V. Piirola, I.A. Kosenkov, A.V. Berdyugin, S.V. Berdyugina, J. Poutanen:
DIPol-UF: Simultaneous Three-Color (BVR) Polarimeter
with EM CCDs, describes the instrument used at the NOT. See
The DIPol-UF polarimeter is capable of making simultaneous
measurements in three passbands, B, V, and R, with high sensitivity.
Either linear or circular polarization observations can be made, but
the calcite unit can be retracted, and the instrument can also be used
as a high-speed simultaneous three-band photometer.
DIPol-UF is not a common-user instrument, but is only
supported during specific periods. Before
applying, prospective users should contact
Dr. A. Berdyugin (firstname.lastname@example.org) at the University of Turku, or
Prof. Dr. Svetlana Berdyugina (email@example.com) at the
Leibniz-Institut for Solar Physics, about the possible use of the
instrument at the NOT.
See here for a more detailed
description of the instrument when mounted at the NOT.
