ABSTRACT:
The illuminator of the invention takes relatively coherent light exiting from a fiber optic cable, and disperses it in an even manner over a wide viewing area of an eye retina, and by securing a transparent material having a light dispersing first surface to face the light output end of the fiber optic cable with an air gap in-between, thus allowing a large light index differential between the fiber material and the light dispersing material.
