Abstract
A pickup tube such as a vidicon has an improved structure for precisely aligning a mesh support electrode relative to a focus electrode. The structure comprises a plurality of focus electrode embossments extending radially outward from the focus electrode and a plurality of mesh support electrode embossments extending radially inward from the mesh support electrode. An insulating ring is molded in situ between the focus electrode embossments and the mesh support electrode embossments. The focus electrode embossments and the mesh support electrode embossments are embedded into the insulating ring.
