Historical background is presented of the U.S. Army's requirement for a high performance, lightweight, night vision goggle for use by helicopter pilots. System requirements are outlined and a current program for development of a third generation image intensification device is described. Primary emphasis is on the use of light precision molded, aspheric plastic optical elements and molded plastic mechanical components. System concept, design, and manufacturing considerations are presented.
