Abstract

PURPOSE:To form an antireflection coating having excellent wear resistance, by a method wherein glow discharge is generated by means of a probe high-frequency power source in a treating chamber to activate MgF2 vapor which is then deposited on a lens made from a synthetic resin, the surface of the lens being coated with glass. CONSTITUTION:The interior of a treatig chamber 1 is kept at a high vaccum of 1X10<-5>-6X 10<-5> Torr by means of Ar, O2 or other gases. At the lower part of the treating chamber 1 there is provided an evaporating source 5 for MgF2 which is irradiated by means of the output electron beam of an electron gun 3. At the upper part of the chamber 1 there is provided a lens 6 made from a synthetic resin. The surface of the lens is previously coated with a glass 6a. There is provided a probe 8 between the lens and the evaporating source. A high-frequency power source 10 is externally provided and has an output of 0.4-3kW. By the action of the high-frequency source on the probe 8, glow discharge is generated within the treating chamber 1 to activate the vapor of the evaporating source 5, and the vapor is deposited on the surface of the lens 6. Then the lens 6 is kept at 90 deg.C for not less than 12hr to form an antireflection coating having excellent resistance to hot water on the lens 6 made from a synthetic resin.
