ABSTRACT:
A light source arrangement has a first light source, a second light source and a dichroic mirror. The dichroic mirror is disposed with the first and second light sources and configured to reflect a predetermined portion of the light emitted from the first light source and to transmit the remaining portion. The dichroic mirror is also configured to reflect light emitted from the second light source so that it propagates in the same direction as the remaining portion of the light from the first light source which is transmitted through the dichroic mirror.
