A device for homogenizing light rays from a light source. The device includes a first multi-prismatic surface, a second multi-prismatic surface, and a reflective housing connecting the first multi-prismatic surface with the second multiprismatic surface. The device may be employed in a liquid crystal display projection system. The system includes, in addition to the device, a parabolic reflective collimator, a lamp centered in the parabolic reflective collimator, the lamp emitting light rays reflected by the parabolic reflective collimator, and a liquid crystal display positioned to receive light rays passing through the first multi-prismatic surface, the reflective housing, and the second multi-prismatic surface.
