Abstract
A film projector has side-by-side lamphouses each containing a xenon light source, light beam reflectors and a condensor lens for reshaping the reflected circular light beams into horizontal ellipsoidal light beams flattened by masking for the projection of stereo images by a pair of projection lenses having their optical axes coincident with diagonally related images of a stereoscopic image pair. Non-stereo images may likewise be selectively projected.
