<p>An illumination system for illuminating a spatial light modulator includes an integrator rod (705) positioned in the light path between an arc lamp and the spatial light modulator. At the input surface of the integrator rod (705), there is positioned a field lens (801, 803) for defocusing areas of turbulence within the arc lamp (701, 703). At the output surface of the integrator rod (705) there is positioned a plate (61) effective to prevent dust being attracted to the output surface of the integrator rod (705). The integrator rod is effective to combine light from two separate light sources (701, 703).</p> |
