Patent ID: 8911088

Claim:
Optical apparatus for retinal photography comprising: a housing fitted to or adapted to be fitted to a camera and defining an optical path that is aligned with the camera lens assembly and extends therefrom to a nose region of the housing, said housing having a projecting handle dimensioned and profiled to be grasped by hand for holding the apparatus in one hand; and a plurality of lens components in said optical path and an illumination source that co-operate to illuminate a retina of an eye in front of said nose region of the housing, and to image the illuminated retina at the image sensor of the camera, wherein said lens components include first and second lens elements that are mounted at spaced locations in the optical path respectively nearer the camera lens assembly and further from the camera lens assembly and cooperate to limit the field of view of the camera to the pupil area of said eye, wherein said nose region ends at a tip of the housing directly in front of the lens elements and the camera lens assembly, and said illumination source is a solid state light source mounted in the optical path between said first and second lens elements but closer to the first lens element, in a manner whereby light emitted by the solid state light source is focused, by the second lens element, at or near the pupil of an eye in front of and spaced from said tip of the housing and thereby illuminates the retina of the eye.
