Abstract

An ophthalmological instrument for stereoscopic examination of the fundus or retina of the eye of a patient, and documentation thereof, as by photographing it. The instrument provides an observation light beam path, and an illumination light beam path. In the observation beam path are various optical elements for producing an image of the fundus at appropriate places, and a beam splitter to split the beam into two parts for stereoscopic viewing. A movable deflector can be shifted to a position to deflect at least part of the beam to a camera or other documentation device.
