Abstract
An optical device includes an optical system and a spectrally selective component arranged in a beam path and configured to spectrally influence light that propagates along the beam path. The spectrally selective component comprises an effective surface having a spectral edge that varies with the incidence site of the light on the effective surface. The effective surface of the spectrally selective component is arranged in the beam path at a point at which a variation of the spectral edge, which is caused by a variation of the incidence angle at which the light is incident onto the effective surface, is at least partly compensated for by an opposite-direction variation of the spectral edge which is caused by a variation of the incidence site. Alternatively, the effective surface is arranged in the beam path at the site of an image of a pupil of the optical system.
