Abstract

A device for outcoupling a portion of the radiation of an observation beam path of a binocular eyepiece for documentation or co-observation that is freely selectable at any time. For the outcoupling, a rotatable supporting unit, the axis of rotation of which is parallel to the axes of the observation beam paths, is arranged in the housing having the binocular eyepiece. Three optical elements are arranged on this supporting unit such that an outer and the middle optical element and, after rotation of the supporting unit, the middle and the other outer optical element are each located in one of the observation beam paths. Here, the two outer optical elements have a beam-splitting effect and outcouple a portion of the observation radiation into a common documentation beam path.
