Abstract: The radiation to be analysed is sent onto an interference filter (6) which selects different portions of the radiation spectrum in correspondence with different incidence angles. The intensity values of the radiation outgoing from the element (6) are stored by a measuring and data processing unit (9) which processes such values with the transfer function of the element to obtain the information on the spectrum.
