To a large extent Bausch & Lomb research has been responsible for the development of anti-reflection coating. In 1939, Bausch & Lomb made the first commercial use of coating when it supplied coated projection lenses for the full-color motion picture, "Gone With The Wind." By 1941, Bausch & Lomb was making Balcote-treated optical instruments for our armed forces. Throughout the war Bausch & Lomb supplied thousands of coated binoculars and other gunfire-control instruments to the Army and Navy, meanwhile working steadily to improve Balcote surface quality.
