Abstract

PURPOSE: To form a protective film of excellent light resistance without deteriorating the optical characteistics, by performing vapor deposition of an organic silicon compound to the aspherical surface of an aspherical lens which has been formed on the optical glass base by use of photopolymerizing resin by the replica method, and subsequently forming a silicon protective film by baking the vapor deposited layer.
CONSTITUTION: An aspherical lens 6 having the aspherical surface 5a which has been formed on the spherical surface of glass by use of a photopolymerizing resin layer 5 of no-land by the replica method is placed in the high vapor deposition unit. KS700 and other silicon compounds are subjected to vapor deposition for 5W15min at the evaporative source temperature of 95W115°C under the high vacuum. As for the organic silicon compound to be used for vapor deposition, the solvent is removed by heating it beforehand. A vapor deposited layer 8 as atomized is formed by said vapor deposition. Subsequently, resulting from heating the aspherical lens 6 for 1.5W2hr at 120W150°C, a protective film of about 100nm in thickness is formed. Accordingly, a protective film of excellent light resistance can be formed without deteriorating the optical characteristics of a lens.
