Shack-Hartmann wavefront sensor for testing the quality of the optics of the 2.5-m SAI telescope

A Shack-Hartmann wavefront sensor for testing the quality of telescope optics based on observations of stars has been developed and constructed. Results of laboratory tests of the sensor and test data obtained on the 70-cm telescope of the Sternberg Astronomical Institute are presented. Estimates of the quality of the optics and of the mirror support of the main mirror of the telescope have been obtained.
