Abstract: A first light source with a first etendue generates a first light beam to travel along a first optical path having an expanded portion formed by a collector optical system. A second light source having a second etendue less than one tenth of the first etendue forms second light, which is conducted by a light guide having a distal section with an end face. The second light is emitted from the end face as a second light beam that travels over a second optical path that resides within the expanded portion of the first optical path due to the light guide being disposed relative to the first optical path from an off-axis direction. An optical condenser receives and directs the first and second light beams to a common exit plane to form the combined light beam.
