Abstract

An ophthalmologic apparatus and a method for the contactless observation, examination, treatment, and/or diagnosis of an eye. The apparatus is structurally based on a fundus camera or an ophthalmoscope. An illumination beam path extends from a first illumination source to the eye and is fitted with a perforated mirror and imaging optics, and an observation beam path extends from the eye to a detector via the imaging optics and through the perforated mirror. The arrangement additionally comprises a beam path for scanning illumination which extends from a second illumination source to the eye and is fitted with a scanning unit, a lens, and a beam splitter in addition to the imaging optics. The scanning unit that is arranged in the beam path for scanning illumination is designed as (an) electrostatically or/and galvanometrically driven bidirectional or unidirectional tilting mirror(s).
