Abstract: A retinal imaging device and illumination module. The illumination module includes a light source to provide an incident beam along an illumination axis, a condenser lens at a spaced apart distance from the light source for condensing the incident beam and emanating a condensed incident beam, a transparent plate at a spaced apart distance from the condenser lens, wherein the transparent plate comprises a light absorber, at least one projections lens system to focus the condensed incident beam, a shield at a spaced apart distance from the projection lens system to yield a first partially blocked beam to form a comea illumination doughnut, and a perforated mirror comprising a hollow cylinder. A portion of the hollow cylinder protrudes out from a reflecting face of the mirror, forming an elliptical stopper to yield a second partially blocked beam to form a pupil illumination doughnut, enabling reflex-free imaging of the retina.
