Paper Abstract

The general theory of diffraction grating was developed in 1974. Although this theory is in wide use, not all the problems associated with the theory have been resolved. We began our work from the particular solution of the problem, which allows us to compensate four aberrations instead of three. For recording of the grating with the compensation of the four aberrations it is necessary to use beams from opposite sides of the blanks. One of the recording beams, going from the back side of the grating blank should be convergent. To form this convergent beam some objective should be used. This objective should not introduce additional aberrations into the system. We suggest to produce objective holographically, like another diffraction grating, made in traditional mounting of recording. This two-steps recording system has six free parameters instead of three in the traditional one. Theoretically it allows to compensate more than four aberrations. Another advantage of this method of recording is in improving of the energetic characteristics since grating have the triangular form of the grooves.
