An apparatus for optically examining security documents (BN) has a detection region (14), in which a security document (BN) is located during the examination, and a spectrographic device (16). The latter has a spatially dispersing optical device (29) for at least partially breaking down optical radiation coming from the detection region (14) into spectrally separate spectral components which propagate in different directions in accordance with the wavelength, a detection device (30) which is spatially resolving in at least one spatial direction and is intended to detect the spectral components, and collimation and focussing optics (28) for collimating the optical radiation which is directed onto the dispersing device (29) from the detection region (14) and for focussing at least some of the spectral components formed using the dispersing optical device (29) onto the detection device (30).
Dispositif d'examen optique de documents (BN) de valeur comprenant une zone (14) d'acquisition dans laquelle se trouve un document (BN) de valeur lors de l'examen et un dispositif (16) spectographique. Celui-ci présente un dispositif (29) optique dispersif dans l'espace pour décomposer au moins partiellement le rayonnement optique en provenance de la zone (14) d'acquisition en composantes spectrales séparées dans le spectre et se propageant dans différentes directions en fonction de leur longueur d'onde, un dispositif (30) de détection à résolution locale dans au moins une direction de l'espace pour détecter les composantes spectrales et une optique (28) de collimation et de concentration pour collimater le rayonnement optique dévié par la zone (14) d'acquisition sur le dispositif (29) dispersif et pour concentrer au moins quelques-unes des composantes spectrales formées au moyen du dispositif (29) optique dispersif sur le dispositif (30) de détection.
