The Given

The transformation of a spherical concave mirror into a parabolic one with the help of elastic bending deformations is considered. The magnitude and direction of the load, which creates the necessary bend for transforming the mirror with the given parameters, are determined. Uneven material removal during machining is replaced by the bend of an optically accurate spherical surface already obtained. The application of the results to the creation of an active control system for the shaping of the surface of a paraboloid of rotation is considered. The proposed finishing technology is aimed at solving the problem of guaranteed obtaining optically accurate surface of a parabolic mirror.
