Abstract
An electromagnetically shielded viewing window for an enclosure including a wire mesh member formed of respective crossing wires bonded between a pair of transparent panels, wherein the wire cross points are joined by nickel/copper plating of the wire mesh without covering the mesh open areas. A dull coating of antiqued silver is applied to the plated wire mesh to reduce window glare. A wire gasket extends around the panel perimeter, and a wire mesh portion projects beyond one of the panels and overlies the wire gasket to reliably ground the wire mesh when mounted to the enclosure.
