Abstract

A spectrometer device includes an optical interference filter which is designed to filter specific wavelength ranges of an incident light beam on passage through the optical interference filter. The spectrometer device also includes a detector device which is designed to detect the filtered light beam. Further, the spectrometer device includes a focusing device with a reflective surface. The focusing device is designed to focus the filtered light beam onto the detector device by reflection on the surface.
