Abstract

A system and method of making a remarkably bright high-gain reflective beam-splitter is presented. Each non-glued together touching layer of the multilayered film of the beam splitter has front and back reflective surfaces that additively increase the brightness. The system can include tables, step-down shelves, cutting bars, gripper units, tension units, a frame, a hoist assembly, and dollies. Constructing the beam-splitter can use grippers that slip slightly, as a function of applied tensioning force, along the trimmed edges of the multilayered film. This slip gripping scheme can result in constructing substantially coplanar sheets of the multilayered film that touch each other face to face and result in removing most of the air between the sheets. The planar integrity of the multilayered film of the high-gain reflective beam-splitter can be maintained at almost any desired display angle even when the high-gain reflective beam-splitter is as large as a standard theatrical stage.
