Image orthicons were used extensively in the early color television cameras such as the RCA TK-40/41, where the increased sensitivity of the tube was essential to overcome the very inefficient, beam-splitting optical system of the camera. [96] [97] The image orthicon tube was at one point colloquially referred to as an Immy.
An image (beam) splitter was used in the TK-40/41 to direct the incoming light into three image orthicon tubes for recording moving pictures in the red, green, and blue component colors. The early cameras required a very large amount of lighting , which caused television studios to become very warm due to the use of multi- kilowatt lamps (a ...
1946 RCA's TK-10 studio camera used a 3" IO – Image Orthicon tube with a 4 lens turret. The RCA TK-30 (1946) was widely used as a field camera. A TK-30 is simply a TK-10 with a portable camera control unit. The 1948 Dumont Marconi MK IV was an Image Orthicon camera. Marconi's first camera was shown in 1938. [4]
The iconoscope was replaced in Europe around 1936 by the much more sensitive Super-Emitron and Superikonoskop, [7] [8] [9] while in the United States the iconoscope was the leading camera tube used for broadcasting from 1936 until 1946, when it was replaced by the image orthicon tube. [10] [11]
The four-tube television camera, intended for color television studio use, was first developed by RCA in the early 1960s. [1] [2]: 96 In this camera, in addition to the usual complement of three tubes for the red, green and blue images, a fourth tube was included to provide luminance (black and white) detail of a scene.
In Australia we were using Image Orthicon cameras at least into the 1970's. Fernseh brought out the only solid state Image orthicon camera I know of in about 1968. We referred to the tubes as "IO's". Peter Resch 06:39, 28 April 2006 (UTC)
An image dissector, also called a dissector tube, is a video camera tube in which photocathode emissions create an "electron image" which is then swept up, down and across an anode to produce an electrical signal representing the visual image. It employs magnetic fields to keep the electron image in focus, and later models used electron ...
Later thermionic vacuum tubes, mostly miniature style, some with top cap connections for higher voltages. A vacuum tube, electron tube, [1] [2] [3] [thermionic] valve (British usage), or tube (North America) [4] is a device that controls electric current flow in a high vacuum between electrodes to which an electric potential difference has been applied.
