An apparatus for optical analysis of value documents (BN) possesses a recording area (14) in which a value document (BN) is located during analysis, and a spectrographic device (16). The latter has a spatially dispersing optical device (29) for at least partly decomposing optical radiation coming from the recording area (14) into spectrally separate spectral components propagating in different directions according to the wavelength, a detection device (30) locally resolving in at least one spatial direction for detecting the spectral components, and a collimating and focusing optic (28) for collimating the optical radiation directed from the recording area (14) onto the dispersing device (29) and for focusing at least some of the spectral components formed by means of the dispersing optical device (29) onto the detection device (30). |
