A system for homogenizing the intensity profile of light includes a plurality of fiber coupled light sources for emitting fiber output beams from fiber output ends, and a light pipe optically coupled to the fiber output beams for producing a uniform light pipe output beam, an interleaver that transmits a first set of fiber output beams and reflects a second set of fiber output beams so that the principal rays of the fiber output beams propagate in a common plane, a first optical element for converging the principal rays, and a second optical element for telecentrically imaging the beams into the light pipe such that the principal rays of the beams propagate parallel to each other and the beams are focused in the light pipe in a focal plane transverse to the direction of propagation.
