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.
