Abstract
A shield for admitting laser beams to a target in a reaction chamber while obstructing exit of target ejected debris from the chamber is formed by coating the opposable faces of two supports with a layer of release agent and a coating protecting the release layer. A bead of transparent epoxy compound is then pressed between the two supports to form an epoxy shield. While the shield is on one support a framing holder is epoxied to the shield.
