Kollmorgen Will Supply Lenses for GE Theatre Color Television The Kollmorgen Corp. has been selected !>\ the General Electric Co. lo provide the projection and Schlieren len assemblies for the first production of "Talaria." General Elecbric's revolutionarj color projector. National General Corp.. a 220-theatre movie exhibitor plans to use the Talaria projector in a nationwide theatre TV network. I In quarter-million dollar award l>\ General Electric to Kollmorgen for the production of projection and Schlieren lenses was made after competitive bidding l>\ major projection lens manufacturer in the United States. Vmong factors governing selection were the ahilit\ to produce complex precision lenses possessing ultra-high resolution, linearity, uniformity and contrast, plus a proven "quick-reaction" capability . "Talaria"" has a wide range ol possible uses outside the commercial entertainment field, including medical and other instruction, military briefings, and national conventions. I ntil development of the projector l>\ Genera] Electric, display of TV pictures on full size 25 l>\ 33 ft. -i reens with adequate brightness wa> limited to black and white. Previously, most color systems were limited lo screens about one-fourth this size. Talaria provides a color picture with characteristics that compare verj lavorabbj with color film. The key factors which make possible the capabilities of this projector are the development of a special control fluid, the development of a novel light gathering ~\-tem to utilize the ver\ high light output of a 5-kw xenon arc lamp, and a simplification of the projection optics wherein all three primary colors are projected with only two output light beams. This dual-beam method results in a simpler and more reliable projector. and substantial!) simplifies the problem of achieving and maintaining precise color registration. This is particularly important for largescreen projection where minute errors would be sreatlv magnified. The Talaria projector has a highpower light source and an optical projection system similar to that of a motion picture projector. But in place of the printed motion picture film, a thin laser of viscous fluid is used. This control fluid was developed bj General Electric for this particular application and has unique electrical. mechanical and optical properties. This control layer is continuously scanned b\ an election beam in the same manner a> the phosphor on the face ol the picture tube in a conventional TV set. But instead of producing a picture directly on the control laser, the scanning process controls the light from the lamp which passes through the control laser in such a manner that a live picture is instantaneousl) produced on a large screen in lull color and brightness. In addition to producing high speed 35mm projection lenses for the motion picture industry, and projection lenses for Cinerama, Kollmorgen produces sophisticated optical alignment instrumentation, submarine periscopes for the \av\. and a variety of optical-mechanical and electronic instruments for the militarv and industry. iP Norelco projection equipment Available from leading theatre supply dealers North American Philips Co., Inc.
