Equiangular-spiral non-loss bent lightpipe and its applications - art. no. 63420S

Abstract

A novel bending lightpipe operation scheme with an arbitrary bent angle without light leakage is illustrated in details. Possible applications to a light-splitting element that could split light flux with specified separation ratio, and a light-mixing element that could mix light fluxes from several ports of entrance without light leakage are also shown with case demonstration.
