Abstract

A visualization apparatus for a surgical site includes a recording unit for recording an image of an object arranged in a focal plane of the recording unit. The recording unit has a lens having an optical axis that intersects the focal plane at a point P. An electronic image representation unit has an image surface for reproducing the recorded image and point P is reproduced at image point P′. A mirror unit has a mirror surface, which has a center point S and is arranged relative to the image surface such that the reproduced image is reflected by the mirror surface. The focal plane, image surface and mirror surface are arranged relative to one another such that an observation point B results for which the following applies:−2 D<Φ1−Φ2<+2 D;wherein:Φ1=−1/d1 Φ2=−1/d2 d1=distance PBd2=distance P′S+distance SB.
