Abstract
An integrating rod ( ) for combining light beams from two or more sources. A first light beam ( ) enters the integrating rod through a first entrance face ( ) to a first reflecting face ( ). The light is reflected by the first reflecting face ( ) and travels along the major axis ( ) of the integrating rod ( ) to an exit face ( ). A second light beam ( ) from a second light source enters the integrating rod ( ) through a second entrance face ( ). The second light beam may be reflected by a second reflecting face ( ) and travels along the major axis ( ) to the exit face ( ). The two light beams experience multiple reflections as they travel along the integrating rod and leave the integrating rod ( ) through the exit face ( ) as a single homogenous light beam.
