An illumination apparatus has first and second optical condenser systems sharing a common aperture. The first optical condenser system has a first solid-state light source having a first spectral band and a first curved surface spaced apart from the first solid-state light source and treated to reflect the first spectral band along a first optical path to exit at the common aperture and to pass light outside the first spectral band. The second optical condenser system has a second solid-state light source having a second spectral band and a second curved surface disposed behind the first curved surface with respect to the first and second light sources and treated to reflect the second spectral band along a second optical path to exit at the common aperture.
