Abstract
Apparatus for illuminating the fundus of an eye with a scanned sample beam of radiation. An embodiment of the present invention is an optical system which includes three, separated radiation path systems--a tilted illumination path system, a decentered observation path system, and an optical path system--which are combined by a beamsplitter into an ocular lens. In accordance with the present invention, an illuminating path provided by the illumination path system and an optical beam path provided by the optical beam path system are obliquely oriented with respect to the optical axis of the ocular lens.
