1. An illumination system, comprising:

  • a light source having a non-radially symmetrical aperture, the aperture having a longer dimension and a shorter dimension, the light source producing illumination with a non-radially symmetrical angular intensity distribution having a larger angular dimension and a smaller angular dimension; and

    an integrator having an entrance end optically connected to the light source and an exit end having a longer dimension and a shorter dimension, the integrator being disposed so that the longer dimension of the exit end is substantially aligned with the larger angular dimension of the illumination produced by the light source at the entrance end of the integrator.
