Patent ID: 8716824

Claim:
An article comprising an electrically conductive and selectively passivated grid pattern having a height of 50 Å to 40,000 Å, the electrically conductive and selectively passivated grid pattern comprises one or more metal layers, the one or more metal layers are joined to an activated base by one or more bonding layers and a top coat covers the electrically conductive and selectively passivated grid pattern, wherein the electrically conductive and selectively passivated grid pattern is passivated with a layer of platinum, palladium or electrolytic gold and the top coat is joined to the activated base at interfaces of the top coat with the activated base to encase the passivated grid pattern, the top coat and the activated base are of the same material, the activated base and top coat are composed of zinc sulfide, water-clear zinc sulfide or zinc selenide, and the article has multi-aperture operation of 55% to 90% radiation transmission in the 3 micron to 10 micron range, or 45% to 90% radiation transmission in the 0.9 micron to 3 micron range.
