Abstract
A spectroanalytical system includes entrance aperture defining structure for receiving radiation to be analyzed along a first path; collimating structure in the first path for providing collimated radiation along a second path; fixed refraction structure in the second path for spatially separating (refracting) radiation in the second path in a first direction as a function of wavelength; fixed echelle grating structure in the second path for spatially separating the refracted radiation as a function of wavelength in a second direction orthogonal to the first direction and directing the orthogonally dispersed radiation in a beam along a third path that does not pass through the first refraction structure; and two-dimensional array detector structure for detecting the beam of orthogonally refracted radiation.
