<p>A system (20) adapted for coupling to an optical conduit (22) provides an input or output port for the transmission of radiant energy to or from the conduit over a spherical angle greater than a hemisphere. The system includes a base support element (21) for holding an end portion of the conduit, typically an optical fiber, and includes a cavity (26) which surrounds the end portion of the conduit. The cavity is provided with an internal reflecting surface (26A). An end of the cavity is closed off with a dome-shaped transparent scattering body (24) having a cylindrical wall, wherein the end of the dome (30) terminates in a surface of revolution such as a hemisphere or prolate ellipsoid.</p> |
