Abstract:
An apparatus for non-contact examination of an eye comprises for illuminating and imaging the eye: an apparatus objective of a positive optical power and a positive spherical aberration which illuminates and images an angle wider than a cross section of the zone I of the retinal vasculature, the apparatus objective being common to the imaging and the illumination the optical paths of which are deviated from each other in the examination apparatus; and a secondary lens unit, which is located behind the apparatus objective in the optical path in a direction of the imaging, modifies at least one of the following optical features: lateral color aberration, astigmatism, field curvature and coma caused by the apparatus objective, and focuses the imaging radiation modified by the secondary lens unit on an image sensor for forming an image of a retina of the eye.

Claim (Index 7):
The apparatus of  claim 3 , wherein the third lens sub-unit is further configured to reduce coma of the first lens sub-unit, axial color aberration of the first lens sub-unit, and spherical aberration of the first lens sub-unit.
