ABSTRACT:
A rod integrator, which has a light incident face and a light exit face, inclines its axis at a predetermined angle with respect to a light emitting direction of a light source. The light incident face is a inclined plane with respect to an axial direction of the rod integrator and deflects the incident light in the axial direction. The light exit face is in parallel with the light incident face and deflects the exit light in a parallel direction to the light emitting direction of the light source. These deflections at the light incident and exit faces bend a light axis of the light.
