Abstract
A scanning monochromator system comprises a housing, structure defining entrance and exit apertures, and a radiation dispersing component in the housing arranged to disperse radiation passing through the entrance aperture into a spectrum for transmission towards the exit aperture. The dispersing element is directly coupled to an electromagnetic drive transducer with the assembly of a rotary component of the drive transducer and the dispersing component being mounted for rotation as a unit about a stationary axis that is perpendicular to the optical axis of the system so that a selected portion of the radiation dispersed by the dispersing component is passed through the exit aperture. The drive transducer is arranged to move a selected portion of dispersed radiation at the exit aperture over a wavelength range of at least 3000 angstroms with a reproducible accuracy of better than 0.03 angstroms in less than one second.
