Abstract:

The purpose of the report is to determine the advantage of using binoculars for night seeing. In order to appraise the improvement in vision quantitatively and determine the relative contributions of objective lens diameter and power to this improvement, experiments were carried out using the M3 6 x 30GI binocular six power, 30 mm objective lens diameter Navy 7 x 50 binocular and the 10 x 45 B.C. scope. Use of the binoculars by troops on night operation problems confirmed the practical advantages indicated by the experiments. Author
