Abstract

The invention relates to a spectrometer for analyzing the optical emission of a sample by means of pulsed excitation of an optical spectral emission, having an excitation source, a gap arrangement, at least one dispersive element and having detectors for the emitted spectrum, in which two beam paths are provided with two dispersive elements, the first dispersive element of which images the spectrum of the emission onto a number of spatially resolving detectors and the second dispersive element of which images the spectrum of the emission onto a number of time-resolving detectors.
