Abstract
A detection system for an atomic emission spectrometer includes a spherical convex diffraction grating having a radius of curvature which is one-half the radius of curvature of a pair of concave spherical mirrors. The diffraction grating and mirrors are positioned within a chamber such that their centers of curvature coincide at the focal plane to which a plurality of relatively small spaced-apart linear detectors are positioned on opposite sides of an emission entry slit to provide detection of alternate segments of a spectral band of wavelengths of interest.
