Paper Abstract

With mirrors of any aperture, the afocal two-mirror system has no spherical aberration. One mirror is spherical, and the other mirror is always an aspherical surface that is equidistant to the virtual parabolic mirror, the focal length of the latter being equal to the air separation between the mirrors. Therefore, a possibility exists of inspecting the aspherical surface shape by means of the known testing methods of the parabolic mirror. The system under consideration has some important technological advantages in comparison with the well-known Mersen system.
