Abstract
Abstract This invention refers to a combined system of optical devices for photography and stereoscopic vision consisting of an optical box device with two front openings, inner mirrors and prisms, adaptable to the lens of photographic cameras, cinema cameras or TV cameras, to take two optical images produced photographically or printed in books or by luminous projection on a screen, so that the image destined to be seen by the right eye is on the left side, and the image destined to be seen by the left eye is on the right side of the double image.

Claim 1
Independent Claim
251 words
An attachment for use with photographic, television and cinema cameras that simultaneously produces in a unit frame a pair of transposed stereographic images from light reflected by an object, which images can be photographed, televised, or cinematographed with conventional equipment, said attachment comprising: a housing adapted for mounting at the front of the camera, said housing having two horizontally spaced front apertures for the receipt of the pair of light images and a rear aperture for transmitting said images into the object lens of the camera; first mirror means mounted at an angle within said housing at the right of the front aperture for reflecting the light image received through the right aperture of said pair of front apertures toward the interior of the housing at substantially a right angle to the entering image; and second mirror means mounted at the left side of said housing at an angle with respect to said first mirror means for reflecting light inciding from said first mirror means to the left half of said rear aperture, the light image entering at the left aperture of said pair of front apertures crossing the light image reflected from said first mirror means within said housing and passing directly through the right half of the rear aperture without deviation, rotation or inversion of the light image whereby the right image is displayed at the right side of the film plane of the camera and the left image is displayed at the left side of the film plane.
