Abstract

A stereo-examination system for imaging an object 8 is proposed, comprising an objective arrangement 3 having an optical axis 5 and an object plane 7 for positioning the object 8 to be imaged, wherein the objective arrangement 3 receives an object-side beam bundle 11 emanating from the object plane 7 into a solid angle region 9 and converts the same into an image-side beam bundle 13, a selection arrangement for selecting at least a pair of partial beam bundles 19, 20 from the image-side beam bundle 13, and an image transmission apparatus 51, 52 for generating a representation of images of the object 8 provided by the partial beam bundles 19, 20. The stereo-examination system is distinguished in that the selection arrangement is provided for displacing a beam cross-section of at least one of the two partial beam bundles 19, 20 relative to a beam cross-section of the image-side beam bundle 13, a controller 49 being provided for controlling the selection arrangement to displace the beam cross-section of the at least one partial beam bundle 19, 20 in circumferential direction about the optical axis 5.
