Abstract
The invention relates to an ophthalmoscope for examining the fundus of an eye of a patient, which comprises at least one illuminating device producing at least one illuminating beam, in addition to an imaging lens system which can be associated with the illuminating device and which images the illuminating beam onto the fundus of the eye of a patient; also comprising an observation device, wherein the imaging lens system images an observation beam onto the fundus of the eye, said observation beam being produced by reflecting the illuminating beam; also comprising a diaphragm arrangement introduced into the illuminating beam and the observation beam, whereby the gap of said diaphragm can be variably modified and synchronized. The invention is characterized in that the imaging lens system is formed in such a manner that an intermediate focal plane is created along the illuminating beam and the observation beam, wherein the fundus of the eye and the illuminating device are imaged, so that the intermediate focal plane is imaged infinitively, and so that the infinitively formed intermediate focal plane is imaged on an image plane of the observing beam, wherein the observation device is arranged.
