Abstract
Abstract An optically transparent article is prepared from an optically transparent first piece and an optically transparent second piece. A channel pattern is scribed into a surface of the first piece to a preselected depth. A metallic stripe pattern is deposited into the channel pattern, with the thickness of the metallic stripe pattern being less than the depth of the channel pattern. The second piece is placed over the first piece and sealed thereto at a peripheral boundary such that the second piece does not contact the metallic stripe pattern. A bus connection is optionally made to the metallic stripe, preferably from the periphery of either the first or second piece.
