Abstract
Optical projection apparatus is disclosed for generating a planar light beam of substantially uniform intensity from a nonplanar multi-element light source projecting a beam having a generally Gaussian intensity distribution. In the preferred embodiment, an optical integrator rod having a faceted end face is used to essentially invert the cross-sectional intensity of the beam entering the entrance face so that when the beam leaves the exit face it has a generally uniform intensity. The body of the integrator rod serves to homogenize the nonplanar source into an exiting beam having substantially planar characteristics.
