Paper Abstract

A concave spherical ruled diffraction grating with a curved nonequidistant grooves is shown to give a stigmatic image of for the three wavelengths, however, unlike the holographic gratings, the stigmatic wavelengths can be chosen in wide limits. A special stigmatic aspherical ruled grating is proposed.
