Abstract

An apparatus for obtaining an image of a retina has an optical relay that defines an optical path and is configured to relay an image of the iris along the optical path to a pupil; a shutter disposed at the pupil and configured to define at least a first shutter aperture for control of light transmission through the pupil position; a tube lens disposed to direct light from the shutter aperture to an image sensor; and a prismatic input port disposed between the shutter and the tube lens and configured to combine, onto the optical path, light from the relay with light conveyed along a second light path that is orthogonal to the optical path.
