Abstract: A multiple total reflection optical device is disclosed with angled ends on optical wave guides in a bundle of optical wave guides. In one embodiment a photocathode imaging system is disclosed wherein the terminal fused plate of a fiber optic bundle is selectively etched to produce a taper at the end of each fiber which is then coated with a photocathode material. Light conducted through the fibers undergoes multiple total reflections down the terminal taper and is dissipated with high efficiency in the photocathode material. The tapered ends can be cones, corner cubes or other shapes.
