ABSTRACT:
A television pick-up tube includes a mesh assembly comprising a pair of superimposed support members having mutually adjacent support surfaces with a mesh electrode secured therebetween. Each of the support members has a centrally disposed aperture therethrough. The apertures are of a different size so that a portion of the support surface of one of the support members extends radially inwardly of the aperture in the other support member. The radially inwardly extending portion of the support surface has a fusion-resistant film of material thereon to prevent the mesh electrode from sticking thereto during the mesh assembly procedure. A method for forming the fusion-resistant film is also disclosed.
