The Image Orthicon

  • R. W. Redington
Part of the Optical Physics and Engineering book series (OPEG)


The image orthicon (IO) was developed during World War II to solve some of the problems of its predecessors in the camera-tube family. These included poor sensitivity, spurious signals, and unstable operation. The solution was good enough that it made commercial television practicable, and in fact good enough that the IO was the best camera tube available for over twenty years. Figure 1 shows a schematic cross section of an image orthicon. The tube has an image section, a storage target, a low-velocity reading beam, and an electron multiplier to amplify and return the beam signal.
