Abstract

An improved mounting for a rotating diffraction grating assembly as used in a spectrophotometer directly connects the grating to the galvanometer that rotates the grating. The galvanometer is gimbally mounted on a plate so that its position, and that of the grating, can be adjusted so that the plane of dispersion of the grating passes through a desired point when the grating is rotated.
