Double Wedged Wollaston Type Polarimeter Design and Integration to RTT150-TFOSC; Initial Tests, Calibration and Characteristics / Helhel, S., Khamitov, I., Kahya, G., Kaynar, S., Bayar, C., Gumerov, R // Experimental Astronomy, 2015, V.39, pp.695-604, ISSN: 0922-6435 (Print) 1572-9508 (Online) DOI 10.1007/s10686-015-9468-8.
    Аннотация The observational facility of 1.5m Russian-Turkish Telescope RTT150 including highly precise positional measurements, photometry and spectroscopy has been broadened with polarimetry. New device was made on the base of Double Wedged Wollaston of well known dual-beam technique. The optic unit was integrated to TFOSC system which is a main telescope detector. Newly designed TFOSC-WP polarimeter capability was investigated by observations of set non-polarized and strongly polarized stars. The recommended working area with linear behavior of instrumental intrinsic polarization is determined as 1 by 5 arcmin in equatorial coordinate system. The instrumental systematic error of polarization degree is 0.2% and position angle is 1.9 degree. The polarimeter integration to the RTT150 has increased its capabilities in ground-based observational support of present and future astrophysical space missions such as GAIA and SRG, which is one of a primary goal of the telescope.
