Abstract:
1. An optical homogenizing and beam splitting apparatus, comprising: a one-piece hollow tubular body having a first leg, a second leg, and a third leg joined together to form a closed Y-shaped junction, each leg having a polygonal cross-section and a reflective interior surface, wherein the first leg is configured to receive an input light beam having a first intensity that is reflected within the first leg to provide a first leg output light beam at the closed Y-shaped junction, the first leg output light beam being split and reflected into the second leg and the third leg at the closed Y-shaped junction without use of optical components to provide, after reflection in the second leg and the third leg, a second leg output light beam and a third leg output light beam, wherein each of the second leg output light beam and the third leg output light beam has a homogeneous top hat profile and a second intensity equal to one half of the first intensity of the input light beam.
