Abstract

Basic equations of the holographic grating are expanded to those of a new holographic grating produced by recording the interference fringes of two aspherical beams. Aberration terms peculiar to this recording configuration show the possibility of the additional compensation of aberrations over the conventional holographic gratings recorded with plane or spherical beams. To confirm this advantage, we designed and fabricated some aberration-corrected blazed holographic gratings for use with a Seya-Namioka and a Czerny-Turner monochromators, and a polychromator suitable for an array detector. The experimental results indicated that the usefulness of our method to enhanse resolution and throughput of spectrometers.
