ABSTRACT:
A separate mesh vidicon in which in order to reduce voltage pick-up from the scanning field by the conductor system which makes connection to the mesh and at the same time provide a tube which is relatively insensitive to rotation about its axis when positioned within its scanning yoke, connection to the mesh is made within the area occupied in operation, by the scanning field, by a cylindrical conductor surrounding the usually provided cylindrical anode, the remainder of the connection path being provided by a number of conductors arranged symmetrically about the axis of the tube, and an external removable link is provided bridging between the mesh terminal pin and the anode terminal so that the tube may be operated at will as a separate or integral mesh tube.
