ABSTRACT:
A fiberoptic-lighted optical apparatus for use in combination with a camera to photograph the convex surface of the iris of the eye for optimum depth of field and resolution, wherein the apparatus includes two separate fiberoptic light wands which are arranged to be positioned in close proximity to the eye and used to shape and accommodate the radius configuration of the eye, so that most of the light pattern therefrom is located in or adjacent to the pupil of the eye, each fiberoptic wand being selectively adjustable to be lighted by a quartz Halogen lamp, including a synchronized electronic flash tube which is placed in the focal point of the quartz Halogen light source, to provide a wide variety of lighting effects for selectively lighting either side of the eye for in-depth photography.
