Abstract:
1. A white light splitting and homogenizing apparatus, comprising: a hollow tubular body having a polygonal cross-section and a highly reflective interior surface, the body including an input end portion, a first output leg portion, and a second output leg portion, the input end portion being configured to receive white light having a Gaussian profile and to reflect the white light within the input end portion to produce a homogenized input beam; a first filter configured to receive the homogenized input beam and to produce a first reflected beam and a first transmitted beam, the first reflected beam being reflected within the first output leg to produce a first homogenized output beam having a first wavelength characteristic and a top hat profile; and a second filter configured to receive the first transmitted beam and to produce a second reflected beam that is reflected within the second output leg to produce a second homogenized output beam having a second wavelength characteristic and a top hat profile.
