Abstract
Relief diffraction gratings were produced holographically in Shipley photoresist and castings of these gratings molded in an epoxy resin. The diffraction efficiencies of the epoxy resin gratings were measured when the medium on the opposite side of the relief profile was, respectively, air, water, carbon disulfide–benzene mixtures, and solid nitrosodimethylaniline. Fair agreement was obtained with theory; the large dispersion of the aniline-filled grating resulted in a novel-type grating device having a large diffraction efficiency in the green and a small efficiency elsewhere in the spectrum.
