Abstract

Requirements exist within the military for improved binoculars providing the optical performance of existing standard instruments but with significantly reduced weight and bulk. Prototypes of a 6×20 minimum size binocular and of a 7×50 lightweight binocular developed by U. S. Army Ordnance in response to the foregoing requirements are now being evaluated by the U. S. Army to determine their suitability for field use.

In this paper, the optical performance and physical characteristics of these new binoculars will be described.
