    Abstract: A graduated filter arrangement, an optical arrangement having a graduated filter arrangement, and uses of a graduated filter arrangement, where the filter arrangement has a graduated filter that is moveable in relation to a beam path and is provided in an intended filter plane, and a mirror in a mirror plane. The mirror plane and the intended filter plane are aligned fixedly in relation to one another and relative to one another in such a way that a beam of light rays that is incident at an angle of incidence along the beam path is reflected, at least in part, between the graduated filter and the mirror in such a way that there at least is a two-fold deflection of the incident light ray by the graduated filter arrangement and the reflected light ray is reflected as a beam of reflected light rays at a deflection angle.
