Abstract

We present a device using Shack-Hartmann wavefront sensor for measuring concave optical parts. A technique based on the device makes it easy to measure the main parameters of the aspherical equation of concave aspherical mirrors, radius of closest sphere Rv and eccentricity ε. The described method allows you to reconstruct the shape of the controlled surface in the form of an equation specified during its manufacture.
