A vidicon tube is a video camera tube design in which the target material is a photoconductor. The vidicon was developed in 1950 at RCA by P. K. Weimer, S. V. Forgue and R. R. Goodrich as a simple alternative to the structurally and electrically complex image orthicon.

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]
G.E. ceased production of its 3 x I.O., the type PC-25 in 1966. Meanwhile, the company had brought out, in 1965, a 4-tube vidicon camera, the GE PE-24, for film scanner use. [33] [34] This was followed by an all-Plumbicon 4-tube camera, the type PE250, which used conventional relay optics, rather than the prism optics of some other colour ...
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.
EMI 2001s on their last day in BBC Elstree Centre Studio C in July 1991. The last programme in the world to use EMI 2001s to record images was EastEnders. The EMI 2001 broadcast studio camera was an early, very successful British made Plumbicon studio camera that included the lens within the body of the camera.
1936 saw the arrival of RCA's iconoscope camera. 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.
Electron gun from an oscilloscope CRT Setup of an electron gun. 1. Hot cathode.2. Wehnelt cylinder.3. Anode. A direct current, electrostatic thermionic electron gun is formed from several parts: a hot cathode, which is heated to create a stream of electrons via thermionic emission; electrodes generating an electric field to focus the electron beam (such as a Wehnelt cylinder); and one or more ...
