Abstract: Disclosed herein is a method for calibrating a spectrometer device. The method includes the following steps: a) illuminating at least one detector device of the spectrometer device with at least one broadband light source through at least one narrow band pass filter having a plurality of predetermined transmission bands; b) generating, by using the detector device, a plurality of detector signals depending on the illumination of step a); c) determining at least one item of wavelength calibration information, where the item of wavelength calibration information includes at least one assignment assigning wavelengths of incident light to corresponding photosensitive elements being responsive to these wavelengths; and d) determining at least one item of stray light calibration information based on the plurality of detector signals. Further disclosed herein are a system for calibrating a spectrometer device, a computer program and a computer-readable storage medium.
