Abstract

An apparatus for recording an image of an object field on a body from outside of the body has a shank and an optical unit. The optical unit includes an observation optical unit for recording the image of the object field and is rotatable about an axis of rotation. The observation optical unit has a first stereo channel and a second stereo channel that each has one objective and at least one electronic image recorder. The observation optical unit includes at least one filter that is swivelable into a beam path of the observation optical unit. The at least one filter is swivelable about a swivel axis that is substantially perpendicular to the axis of rotation. At least one filter is swivelable into a beam path of the observation optical unit and into a spatial region arranged laterally with respect to the beam paths of both stereo channels.

First claim

What is claimed is:

1 . An apparatus for recording an image of an object field on a body from outside of the body, the apparatus comprising:
a shank; and an optical unit arranged at a distal end of the shank, the optical unit comprising an observation optical unit for recording the image of the object field and being rotatable about an axis of rotation that is at least substantially parallel to a viewing direction of the observation optical unit, wherein the observation optical unit has a first stereo channel and a second stereo channel, the first and second stereo channels having an objective and at least one electronic image recorder, wherein the observation optical unit comprises at least one filter that is swivelable into a beam path of the observation optical unit and swivelable therefrom, and wherein the at least one filter is swivelable about a swivel axis formed substantially perpendicular to the axis of rotation.

2 . The apparatus as claimed in claim 1 , wherein an optical axis of the objective in the first stereo channel and an optical axis of the objective in the second stereo channel lie in a common plane and wherein the swivel axis lies at least substantially in the common plane or in a plane substantially parallel thereto.

3 . The apparatus as claimed in claim 1 , wherein the observation optical unit comprises a first filter and a second filter, wherein the first filter is swivelable into a beam path of the first stereo channel and swivelable therefrom, and the second filter is swivelable into a beam path of the second stereo channel and swivelable therefrom.

4 . The apparatus as claimed in claim 3 , wherein the first filter is swivelable in and out between the objective and the at least one image recorder of the first stereo channel, and the second filter is swivelable in and out between the objective and the at least one image recorder of the second stereo channel.

5 . The apparatus as claimed in claim 4 , wherein the first filter and the second filter are arranged on a common swivelable filter carrier.

6 . The apparatus as claimed in claim 3 , wherein the first filter and the second filter have substantially the same spectral characteristics.

7 . The apparatus as claimed in claim 3 , wherein the first filter and the second filter have different spectral characteristics.

8 . The apparatus as claimed in claim 1 , wherein the at least one filter is swivelable via a motor.

9 . The apparatus as claimed in claim 1 , wherein the optical unit comprises at least one sensor for detecting a swivel position of the at least one filter.

10 . The apparatus as claimed in claim 1 , wherein the at least one sensor is a magnetic sensor and/or a proximity switch.

11 . The apparatus as claimed in claim 1 , wherein the observation optical unit comprises a focusing device.

12 . The apparatus as claimed in claim 1 , wherein the optical unit comprises a marker light source.

13 . The apparatus as claimed in claim 1 , wherein the first stereo channel and the second stereo channel each comprise at least one further electronic image recorder and a beam splitter.

14 . The apparatus as claimed in claim 1 , wherein the optical unit has a hermetically sealed embodiment.

15 . The apparatus as claimed in claim 1 , wherein the observation optical unit comprises at least one filter, which is swivelable into a beam path of the observation optical unit and swivelable therefrom into a spatial region arranged laterally with respect to the beam paths of both stereo channels.

16 . The apparatus as claimed in claim 1 , wherein the at least one filter is swivelable about a swivel axis directed substantially parallel to the axis of rotation.

17 . The apparatus as claimed in claim 1 , wherein the body is a human body or animal body.
