Abstract: A spectrometer has an entry aperture for coupling in electromagnetic radiation to be spectroscope, a refractive or diffractive optical element arranged such that electromagnetic radiation which is coupled in through the entry aperture is incident on the refractive or diffractive optical element to be spectrally split there, and at least two individual detectors which, for the detection of different spectral ranges of the split electromagnetic radiation, are arranged next to one another in the direction of the spectral splitting of the electromagnetic radiation. Electromagnetic radiation from a predetermined ultraviolet wavelength range is directed onto one of the individual detectors by the optical element and electromagnetic radiation from a predetermined blue wavelength range is directed onto another of the detectors by the optical element. Electromagnetic radiation from the intermediate wavelength range between the predetermined ultraviolet wavelength range and the predetermined blue wavelength range are not detected.
