The present invention provides a device and method to efficiently turn
light from an optical fiber around a corner while avoiding the
frustrated-TIR loss that would occur if the fiber were bent. The
invention uses non-imaging optics which efficiently deal with beam
divergence half-angles less than 90.degree.. By recognizing that most
light from a fiber optic source will have a divergence half-angle of less
than 90 degrees, a practical solution is achieved using non-imaging
optics.
