ABSTRACT:
A stereoscopic viewer using a prism to separate the two images and capable of producing a stereoscopic effect from one image due to refraction in the prism; in one embodiment a V shaped slide mount containing one transparency normally oriented and a second laterally reversed may be mounted in a housing causing a light switch to close, activating a bulb which illuminates a diffusing glass which lights the transparencies, the light passing through the transparencies to refract through the prism and converge on a front magnifying lens from which a viewer can see the image stereoscopically; a single slide may also be inserted in the viewer and a black flexible slide switch operated to cover one face of the prism and to light the bulb to show the image stereoscopically; movie films may be projected on screens and the images refracted through a prism and magnified through a magnifying lens to permit a viewer to see stereoscopic movies.
