Vidicon tube 2 ⁄ 3 inch (17 mm) in diameter A display of numerous video camera tubes from the 1930s and 1940s, photographed in 1954, with iconoscope inventor Vladimir K. Zworykin. Video camera tubes are devices based on the cathode-ray tube that were used in television cameras to capture television images, prior to the introduction of charge ...
A Farnsworth image dissector tube. 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.
The camera had an image orthicon tube for the luminance channel and three vidicon tubes for the colour channels. In addition, the camera was fully transistorized, apart from the four pick-up tubes. The camera went into full production in 1963 and sales of several hundred of the model were achieved over the next few years.

The camera section held the lens and camera tube pre-amplifiers and other necessary electronics, and was connected to a large diameter multicore cable to the remainder of the camera electronics, usually mounted in a separate room in the studio, or a remote truck. The camera head could not generate a video picture signal on its own.

But the magnetic focusing for video camera tubes invented by Farnsworth in 1928 --via a long focusing coil placed along the tube-- survived the image orthicon era and it was a main ingredient in the vidicon and similar tubes; see the vidicon's diagram in the article.
Albert Rose (30 March 1910 – 26 July 1990) was an American physicist, who made major contributions to TV video camera tubes such as the orthicon, image orthicon, and vidicon. [ 1 ] [ 2 ] According to the New York Times, Albert Rose is credited as the father of the orthicon television camera tube, which was developed during World War II, and ...
