Assignee: KARL STORZ SE & CO. KG
Field: Optics (Instruments)
Classification: CPC G  A | IPC A  G

Claim 16:
17. A method to generate a stereo image of an object field comprising:
bringing an optics unit of an optical observation instrument into a spatial position, the optics unit including 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, the optics unit configured 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 paths extend through the objective arrangement, and a retaining apparatus, on which the optics unit is mounted, the optics unit rotatable about a first axis of rotation, the first axis of rotation at least approximately corresponding to an axis of the objective arrangement, wherein the retaining apparatus comprises a retaining bracket, which engages over the optics unit, which is arranged inside a housing, and on which the optics unit is mounted to be a rotatable about the first axis of rotation, wherein a optical deflection element is retained at an object-side end of the retaining bracket, and wherein the optical observation instrument has a viewing direction that is angled in relation to the axis of the objective arrangement and comprises the deflection element, arranged on an object-side of the objective arrangement, and configured to deflect the first and the second beam paths into the objective arrangement,
setting a viewing direction to the object field,
setting an alignment of a stereo basis by rotating the optics unit about the first axis of rotation,
recording stereo half images by the at least one electronic image recorder of the optical observation instrument, and
displaying the stereo half images on a display device.
