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 remarkably wide variety of tube and similar sockets is listed and described, with some informal application notes, at a commercial site, Pacific T.V., [28] including nuvistor, eight-pin subminiature, vidicon, reflex klystron, nine-pin octal-like, 10-pin miniature (two types), 11-pin sub-magnal, diheptal 14-pin, and many display tubes such as ...
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.
Two iconoscope tubes. The type 1849 (top) was the common tube used in studio television cameras. The camera's lens focused the image through the tube's transparent "window" (right) and onto the dark rectangular "target" surface visible inside. The type 1847 (bottom) was a smaller version.
This is a list of vacuum tubes or thermionic valves, and low-pressure gas-filled tubes, or discharge tubes. Before the advent of semiconductor devices, thousands of tube types were used in consumer electronics.
The aims of the designers of the camera were, firstly, to produce a camera that was more tolerant to mis-registration and, secondly, to achieve a lighter camera by using smaller vidicon tubes to replace some of the large heavy IO tubes. The camera had an image orthicon tube for the luminance channel and three vidicon tubes for the colour ...
