Paper Abstract

Two plates are placed in an exposure frame using a vacuum applied around the periphery while atmospheric pressure is maintained on the outside surfaces to force the plates into contact without trapped gas between. Integrated watt-second exposure is used with a controlled coherence source, allowing micron images.
