Orthicon Portable Television Equipment

Recently developed orthicon portable television equipment is described. Because of the greater light sensitivity of the orthicon, it is expected that the equipment will fill a need for lightweight equipment to be used under adverse light conditions. Among the novel features of the design are the use of a forced-air-cooled transformer in the regulated power-supply unit, an all-electronic synchronizing generator, gamma control, and keyed diodes for black-level setting. The units required for a one-camera setup are: camera and tripod, camera control unit, power-supply unit, pulse unit, and shaping unit. The total weight, exclusive of camera cable, is 370 pounds and the power required is 1250 watts.
