The record contains a lens, which is part of a stereo projection system, produced for a presumed market in commercial stereo imaging. It included lenses, and special 16mm motion picture projectors, projection screens and other dark room equipment. With the help of the specialists in the Technical Photography Group, the lens was adapted the lens to fit a more flexible 16mm projector, and a special film printing procedure was developed to map images from 35mm to 16mm. The images were placed side by side on the 16mm film. Referring to the images as left eye and right eye, each image path contained a special polarizing filter. The images were projected onto a metallized viewing screen. Use of polarizing glasses ensured that the viewers eyes each saw only that portion of the in tire image intended for the eye. The SOMCO projection lens allowed adjustments of left-right image spacing (inter-pupilary distance) and focus.
