  • Fiber optic coupler with concave spherical reflecting elements
    Patent number: 4156556
    Abstract: An optical coupler transfers light energy signals relative to an optical h which includes a fiber optic cable. A body member includes first and second ports at opposite ends for supporting first and second terminals of the fiber optic cable in laterally offset alignment relative to each other. First and second reflective elements, preferably of concave spherical configuration, are supported within the body member for collecting and reflecting light energy transmitted through the first and second terminals of the fiber optic cable. The first and second reflective elements are so configured and positioned as to transmit collimated light energy between them for completing the optical path between the first and second terminals of the fiber optic cable.
