Abstract
684,854. Diffraction gratings. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Feb. 21, 1951 [March 2, 1950], No. 5361/50. Drawings to Specification. Class 97 (i). [Also in Group V] A diffraction grating comprises a sheet of gelatine into the surface of which the rulings of the grating have been impressed (see Group V). The sheet may be mounted on a glass support and may be used thus as a transmission grating, or may be aluminized or otherwise metallized to make a reflection grating.
