Abstract: A dispersive spectrometer whose dispersive element is aligned such that the direction of dispersion is essentially perpendicular to the collimating plane, which is the plane of the input beam path between the centers of the input slit, the collimating mirror and the dispersive element. As a result of this construction, the lateral spread over which the beam path traverses is reduced, since use is also made of the direction perpendicular to the input beam path plane for the dispersive spread of the beam, and the spectrometer is thus of compact construction.
