ABSTRACT:
A cuspate lens is disclosed having a slope magnitude which decreases from a maximum at a central cusp to a minimum at the periphery. A radially symmetric version of the lens can focus light into a ring, or produce an annular beam. Also disclosed are a fiber optic coupler and an optical slip ring using the cuspated lenses.
