A waveguide spectrometer includes at least one substrate layer with at least one waveguide. Each waveguide extends from an inlet face proceeding partly through the substrate layer to a reflecting element. A multiplicity of photo detectors is arranged on a front side of the substrate layer, while the photo detectors are electrically connected to an electronic read out system. The spectrometer can be made lightweight and easier to produce by forming the waveguides as surface waveguides, each showing a longitudinal opening with a width to the front side of the substrate layer between the inlet face and the reflecting element. The photo detectors are in print distributed at the front side on top of the substrate layer at least partly overlapping the longitudinal opening along an overall length of sampled region and the electrical connection of the photo detectors with the electronic read out system is achieved by a multiplicity of printed electrical conductors.
