Claim:
1. A light duct homogenizer, comprising: an inlet light duct having a first surface and an opposing second surface disposed at an inlet light duct height from the first surface; an outlet light duct contiguous with the first surface and having an opposing third surface disposed at an outlet light duct height from the first surface, the outlet light duct height being greater than the inlet light duct height; a first light diverter forming a 45 degree angle between the second surface and the third surface; and a second light diverter disposed parallel to the first light diverter, the second light diverter contacting the first surface and positioned such that a portion of a light beam propagating from the inlet light duct to the outlet light duct that reflects from the second light diverter, also reflects from the first light diverter, and wherein a length of the second light diverter extending in a perpendicular direction from the first surface is less than the inlet light duct height.
