EYE IMAGING APPARATUS WITH A WIDE FIELD OF VIEW AND RELATED METHODS

摘要

An eye imaging apparatus can include a housing, an optical imaging system in the housing, and a light source in the housing to illuminate an eye. The optical imaging system can include an optical window at a front end of the housing with a concave front surface for receiving the eye as well as an imaging lens disposed rearward the optical window. The apparatus can comprise a light conditioning element configured to receive light from the light source and direct said light to the eye. The apparatus can further include an image sensor in the housing disposed to receive an image of the eye from the optical imaging system. In various embodiments, light conditioning element includes at least one multi-segment surface. In some embodiments, the housing is provided with at least one hermitic seal, for example, with the optical window. In some embodiments, time sequential illumination is employed.
