Abstract: A grating drive apparatus for use in a multiple-grating spectrometer is provided. The spectrometer has an entrance slit, an exit port, an optical path between the entrance slit and the exit port, and a plurality of diffraction gratings. Each of the gratings is rotatable about a respective preferred axis for selecting a wavelength during spectrometer operation. The grating drive apparatus includes a turret having a plurality of gratings mounted on it, a mechanical stop assembly, and a drive assembly. The drive assembly causes the turret to engage the stop assembly to rotate the turret and select a grating. The drive assembly also rotates the selected grating to select an operational wavelength.
