Abstract:

This paper describes a method of determining the decentering of an aspheric surface relative to the geometrical center of an astronomical mirror by means of a three-point linear spherometer, also used to determine deviations of the profile of a ground surface from the specified surface. Examples are given of the successful use of the device.
