Coatings from 500 to 10,000 angstrom thick of SiO2 and A12O3 were deposited on polycarbonate lenses. Techniques were established for depositing transparent, glass-like coatings without introducing changes in the visual properties of the lenses. It was discovered that the mar resistance test is not applicable to testing of optical coatings. During the close of the investigation, effort was applied to the pre-liminary design for mass production equipment.
