Abstract
A technique has been developed for measuring the radii of curvature of optical parts. A scheme of the device based on a wavefront sensor is proposed, which is characterized by a minimum measurement error. The theoretical substantiation of the measurement technique is given. A number of methods that make it possible to measure the radii of curvature of optical parts are considered. The reasons for an increase in the measurement error are analyzed. The results of measurements according to the given methodology with an original prototype device are considered.
