Abstract
A spectroanalytical system includes entrance aperture defining structure for receiving radiation to be analyzed along a first path; dispersion structure in the first path for spatially dispersing the radiation as a function of wavelength; exit aperture structure defining a non-elongate aperture for receiving radiation from the dispersion structure; detector aperture structure coupled to the exit aperture structure for detecting selected wavelengths of the dispersion radiation; and wedge-like conditioner structure disposed between the first path and between the dispersion structure and the entrance and exit aperture structures.
