Abstract
The functional and metrological characteristics of a new solar telescope designed to obtain quantitative data on large-scale magnetic fields (LMF) of the Sun are considered. The full automation of measurements, the application of CCD matrices in image scanning and spectra recording systems, and the optical diagram corresponding to the main purpose of the telescope significantly increased the efficiency, quality, and accuracy of measurements of the LMF and expanded the range of tasks in comparison with existing telescopes. The developed automated system of telescope control, measuring system, and software for real-time processing of measurement results make it possible to obtain LMF magnetograms with the required accuracy for about 15 min.
