Abstract
A spectroanalytical system for receiving radiation to be analyzed along a first path includes a grating in the first path with periodic faceted grooves for spatially separating the radiation as a function of wavelength. The blaze angles of the faceted grooves are progressively graded. A multielement detector detects radiation spatially separated by the grating. An optical conditioner is disposed in the first path between the grating and a multielement detector.
