Abstract: An optical emission spectrometer has an excitation device for a sample to be examined, a dispersive element for spectrally decomposing light emitted by an excited sample, a multiplicity of photodiodes, which are arranged such that different spectral components of the emitted, decomposed light are detectable with different photodiodes, and a multiplicity of electronic readout systems for the photodiodes. A respective electronic readout system has a charge storage assembly comprising a plurality of individual charge storage devices, wherein the charge storage devices are interconnectable in cascading fashion, with the result that charges flowing in from an associated photodiode successively fill the charge storage devices. The respective electronic readout system can be used to read the charges of the individual charge storage devices of the charge storage assembly and/or the charges of subsets of the charge storage devices of the charge storage assembly.
