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.
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.

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 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.
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.
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.
The video camera tube invented by Farnsworth in the US patent 2,087,683 is a fully functional Orthicon and anyone who says the opposite is a malicious ignorant. --201.103.48.132 16:48, 6 August 2011 (UTC) Unfortunately there is not evidence that Farnsworth ever transmitted a clear and well focused image with such a tube.
