Abstract
A process is disclosed for simultaneously etching only one side of at least two sheets of glass to reduce specular reflectance on the etched side while improving resolution and process efficiency. In the process, two face to face sheets of glass are aligned and a seal is formed to render the adjacent inside faces of the glass sheets substantially fluid-tight during the etching process. The sealed sheets are then transferred to an etching bath where their outside faces are etched, but their inside faces are not visibly etched.
