Abstract:
1. A spectrometer for analyzing the optical emission of a sample by means of pulsed excitation, the spectrometer having: an excitation source arranged to excite the sample and to cause the emission of an optical spectral emission by the excited sample, a gap arrangement configured to receive the optical spectral emission, at least two dispersive elements configured to receive respective beams output by the gap arrangement in response to the optical spectral emission, and a plurality of detectors for the emitted spectrum, wherein two beam paths are formed within the spectrometer, using the two dispersive elements, each of which dispersive elements is configured to image the spectrum of the emission onto a multiplicity of detectors of the plurality of detectors, the multiplicity of detectors including at least one time-resolving detector configured to detect a time sequence of a single excitation, wherein the multiplicity of detectors includes a number of spatially resolving detectors, a number of further time-resolving detectors, or a combination of spatially resolving detectors and further time-resolving detectors, and wherein the multiplicity of detectors includes one or more spatially resolving detectors that are solid body detectors.
