Abstract

PURPOSE:To produce a reflection preventing film having high light transmittance and high strength with high workability by successively laminating ZrO2, MgF2 and SiO2 on a plastic optical member. CONSTITUTION:A reflection preventing film 1 is formed on a plastic optical member 2 of PMMA, etc. by laminating by vapor deposition a ZrO2 layer 3 with 1/2lambda-1/8lambda thickness (normally 1/4lambda), an MgF2 layer 4 with 1/4lambda thickness and an SiO2 layer 5 in that order. The 3rd layer 5 is provided especially to prevent the deterioration of the 2nd layer 4 and accordingly set at <=1/8lambda thickness that gives no effect to the reflection preventing performance of both layers 3 and 4. In such way, a reflection preventing film is produced with high workability. Such film has the equivalent strength to and higher light transmittance than a film which is obtained by applying a surface reinforcement process on a plastic optical member by means of SiO2 or glass.
