ABSTRACT:
A stereoscopic lens system for simultaneously recording left and right images on longitudinally displaced half-frames of a motion picture film. Left and right images are formed by a pair of adjustable receiving lenses horizontally spaced by the average human interocular distance and vertically spaced by an amount corresponding to the half-frame displacement. Images formed by the receiving lenses are focused onto respective field lenses. These images are in turn directed by front-silvered flat mirrors to the optical elements of a relay lens mounted to the optics body containing the above-described elements. Provision is made for the mounting of accessory receiving lenses and convergence altering optical elements located in front of the receiving lenses.
