ABSTRACT:
The present invention is directed to a device for examining the eye, preferably the fundus of the eye, by an optical system and electronic sensors for image recording in different imaging scales. In the device according to the invention, at least two image recording sensors with different shape factors are swivelably arranged in the imaging plane of the device. These image recording sensors have optically active surfaces of different geometric sizes, an approximately identical number of pixels and preferably the same electronic control and evaluation. The invention described herein requires no additional objectives and the optical adjustment is limited to an individual rigid objective. An exact alignment of the image recording sensors in the imaging plane and manufacturing tolerances can be compensated by adapting the image section by means of software. It is particularly advantageous that the imaging scale is influenced without changing the optical parameters of the system.
