ABSTRACT:
A retinal imaging system includes a light source and optics which receive light from the light source and which transmit the light to produce a beam that is substantially convergent. The beam penetrates a lens of an eye and diverges following penetration of the lens to illuminate an area of a retina of the eye. An imaging device receives a reflection of light from the retina.
