ABSTRACT:
An aspheric mirror in the form of a toric mirror includes a first element having a front surface which defines a spherical reflector and a spaced apart rear surface. The spherical reflector includes a constant radius of curvature, an X-axis with an X-axis radius of curvature and a Y-axis with a Y-axis radius of curvature. The first element possesses a first rigidity factor. A second element includes a front surface sized to mate with the rear surface of the first element along an interface zone. The second element possesses a second rigidity factor. An interface contour device produces a differential cylindrical contour within the interface zone between the first and second elements. The interface contour device is aligned to modify the X-axis radius of curvature of the spherical reflector without significantly modifying the Y-axis radius of curvature. A compression device compresses the first and second elements together to deflect the first element relative to the second element to modify the X-axis radius of curvature without substantially modifying its Y-axis radius of curvature to produce a toric mirror.
