Abstract
An optical pattern that is to be supported for examination is formed on a surface of a substrate, generally glass. Corner brackets are fixedly mounted on the substrate. Each of the corner brackets has a support portion and a housing that mounts a locating ball or sphere that protrudes out of the housing. The housing is connected to the support portion of the respective bracket through a flexure hinge that permits movement of the housing and supported ball in a plane generally parallel to the surface of the substrate having the optical pattern.
