Abstract
As early as 1892 it was known that the reflectivity of polished glass surfaces was reduced and the light transmission increased when a suitable film was present on the surface of the glass. Many efforts to produce such a film artificially met with only partial success. In the past five years, two different methods have been discovered that achieve the desired results. Only one of the processes, however, was satisfactory for commercial application. Great improvements have been made in the durability and weather resistance of the thin films deposited upon the lens surface by this method. Lenses coated by this improved process require no more careful handling than any good lens is entitled to; fingerprints and dust can be removed without detrimental effects to the coating. The thin films can not be scratched with anything less hard than a metal point. By this process, reflectivity can be reduced from an average of 5 per cent for untreated polished surfaces to as low as 0.5 per cent for treated ones. Experiments show that even greater reductions are possible and should be available in the near future.
