Abstract

The invention relates to a beam manipulation device for a scanning microscope, comprising a main colour splitter for coupling excitation light into an illumination beam path and for separating excitation light from detection light of a detection beam path, said device comprising a scanner, preferably positioned on a pupil plane, for scanning the excitation light. The device is characterised in that: an additional optical section is provided comprising optical elements which influence a beam path; at least one pupil plane and/or at least one intermediate image plane is formed in the additional optical section by the optical elements which influence the beam path; and an adjustable selection device is provided for activating either a first beam segment of the illumination and/or detection beam path, or the additional optical section, wherein the first beam segment of the illumination and/or detection beam path does not contain a pupil plane of the illumination and/or detection beam path.
