Abstract: An improved camera tube of the vidicon type has a field mesh accurately mounted between the target and the electron beam gun. The mesh is mounted in a manner to permit accurate spacing and parallel alignment with the target surface and to permit external electrical connections with the field mesh to be made without disturbing the electrical fields within the tube, providing a low inductance contact to the mesh particularly useful in high resolution tubes.
