Abstract

An optical observation instrument according to the invention, in particular a surgical microscope or exoscope, comprises an optics unit with an objective arrangement and at least one electronic image recorder, wherein the optics unit has a first stereo channel with a first beam path and a second stereo channel with a second beam path for recording a stereo image of an object field with the at least one electronic image recorder and wherein the first and the second beam path extend through the objective arrangement. The instrument moreover comprises a retaining apparatus, on which the optics unit is mounted so as to be rotatable about a first axis of rotation, the latter at least approximately corresponding to an axis of the objective arrangement, wherein the optical observation instrument has a viewing direction that is angled in relation to the axis of the objective arrangement and comprises a deflection element, arranged on the object-side of the objective arrangement, for deflecting the first and the second beam path into the objective arrangement. The invention further relates to a method for generating a stereo image of an object field.
