A folded optical path (14) is formed between the entrance window and the exit window or the detector zone. An entrance-side construction element (22) is fixed at the substrate stack such that the entrance window is partially covered and an optical entrance diaphragm (24) is defined. An exit-side construction element is fixed at the substrate stack such that the exit window is partially covered and an optical exit diaphragm is defined. An independent claim is also included for a method for manufacturing a spectral dispersion device.de621patent102010040768
