Abstract

The conditions of obtaining an aberration-free image of a point source formed by an aspherical diffraction grating with straight-line nonequidistant grooves are investigated theoretically. As shown, a perfect geometric image can be obtained, if a radiation source and its image lie on a straight line passing perpendicular to the grating normal and being a rotation axis of a grating surface.
