Abstract

PURPOSE:To branch light to two with a simple construction by combining lenses having a spherical face and a sloping plane with themselves or said lens with a prism, providing a reflecting film or air layer of a different refractive index and allowing the leaking-out light transmit therethrough with tunnel effect.
