We present the “StoP” photometer-polarimeter (Stokes-polarimeter) used for observations with the 1-m telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences since the beginning of 2020. We describe the instrument and its parameters in observations performed in the photometric and polarimetric modes. We demonstrate the capabilities of the instrument through the polarimetry of the blazar S5 0716+714 and compare the results with those earlier obtained with the 6-m telescope.

1米望远镜的斯托克斯极镜

我们介绍了自2020年初以来用于俄罗斯科学院特殊天文台的1-m望远镜进行观测的“ StoP”光度计-旋光计（Stokes-旋光计）。我们在进行的观测中描述了该仪器及其参数在光度和偏振模式下。我们通过blazar S5 0716 + 714的旋光法论证了该仪器的功能，并将其结果与早期使用6米望远镜获得的结果进行了比较。
