Abstract
An ophthalmological instrument having optical elements providing an examination light beam path and an illumination light beam path. The optical elements include an objective for producing an inverted magnified flattened image of the fundus of the eye, and further elements for focusing this image at infinity and projecting it selectively either into an observation tube or into a camera or other documentation device where a record of the image may be made. The illumination beam path includes a source of light and means of projecting this light, via a perforated mirror, into the pupil of the patient.
