A filter for use in combination with a cathode ray tube screen to transmit light and absorb other types of energy comprises a translucent plastic substrate onto which is applied a wire mesh impregnated with a thin layer of a bonding agent which constitutes one surface of the filter. In manufacturing the filter, a thin layer of the bonding agent is deposited on the topside of a platen, and the mesh is pressed into the bonding agent to cause it to impregnate the mesh. The translucent plastic substrate is placed on the impregnated mesh, and pressure is applied between the substrate and the platen to form a laminate. Thereafter, the laminate is cured and separated from the platen, after which it may be placed in a mold and formed into a curved shape.

A method of manufacturing a filter adapted to transmit visible light while absorbing certain other forms of energy, said method comprising the steps of: providing a platen having a topside, depositing on said topside a layer of liquid bonding agent which, when cured, is releasable from said topside,

A method of manufacturing a filter adapted to transmit visible light while absorbing certain other forms of energy, said method comprising the steps of: providing a platen having a topside, depositing on said topside a layer of liquid bonding agent which, when cured, is releasable from said topside, placing in said layer of bonding agent a mesh fabricated of electrically-conductive filaments to cause said bonding agent to impregnate said mesh, laying on said impregnated mesh a translucent plastic substrate, applying pressure between said substrate and said platen, curing said bonding agent to cause the impregnated mesh to adhere only to said substrate and to form a laminate, and separating said laminate from said platen topside.
