Abstract

The original optical design for two steps recording of the holographic diffraction gratings is presented. It gives the combination of the merits of two previously developed methods in one. From one hand, due to recording in two steps, we can use wide possibilities of the aberrations compensation. From another hand, we can record both the gratings - objective and the final grating in spatially incoherent light. This simplifies the technology of the holographic recording. Previously per limit one of the two steps required using of the spatially coherent light. Method does not require using of the additional optics. Both surfaces of the grating - objective blank have spherical form. The blank of the final grating can be plane - concave, which is usual for diffraction gratings. Since the blaze angle of the grating, recorded in the counterpropagating beams is determined by the recording geometry, and the efficiency of the grating depends on the polarization of the incident light, the transmission calculations with taking into consideration the polarization also have been provided. The transmission of the system is optimal for the S polarized light, the addition increasing of the transmission can be achieved by using of the immersion grating - objective.
