ABSTRACT:
A leveling apparatus used in conjunction with a specimen holder and plastic film window material to accurately and consistently form a flat, bubble free analysis window on the open face of the specimen holder. The specimen holder in the form of a shallow cylindrical cup is slightly overfilled and covered by the plastic film. Placement of the mating leveling apparatus over the film squeezes out trapped air bubbles, levels the exposed face of the specimen, draws the plastic film tight over the exposed face of the specimen, and allows easy installation of a film retaining O-ring to maintain the specimen material in a level state within the holder.
