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 ...
The iconoscope (from the Greek: εἰκών "image" and σκοπεῖν "to look, to see") was the first practical video camera tube to be used in early television cameras. The iconoscope produced a much stronger signal than earlier mechanical designs , and could be used under any well-lit conditions.

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 ...
Both cameras are slow-scan vidicon tubes with a selenium sulphur storage surface, and are fitted with eight colored filters mounted on a filter wheel in front of the tube. Pale Blue Dot was taken with the narrow-angle camera, a 1500 mm f/8.5 catadioptric cassegrain telescope whose design was based on the 1973 Mariner mission. [13] [14] [15]
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 ...
