摘要：
We describe a dichroic circular polarization analyzer with a double image slicer providing seven slices for each polarization developed for the Main Stellar Spectrograph of the 6-m telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences. The analyzer is designed for measuring stellar magnetic fields using the Zeeman effect and represents an upgraded version compared to earlier used polarization analyzers. We report the parameters of the analyzer and estimate the accuracy of measurements performed with it.
