The first light source can generate a first light beam having a first
spectral distribution. The first light beam can propagate primarily in a
first direction along an optical axis. A second light source array can be
included, having a second light source that generates a second light beam
having a second spectral distribution. Also included can be a first
dichroic reflector positioned partially in the first and the second light
beams. The first dichroic reflector can transmit a part of the first and
the second light beams. The second light beam can propagate in a second
direction towards a part of the first light source array and opposite the
first direction. Further, a part of the second light beam can propagate
primarily in first direction after being reflected by the first dichroic
reflector.
