Abstract
PURPOSE:To produce with high workability a reflection preventing film having high light transmittance and high strength, by first vapor-depositing ZrO2 and then SiO with oxidizing on a plastic optical member. CONSTITUTION:A reflection preventing film 1 is formed on a plastic optical member 2 of PMMA, etc. by first vapor-depositing a ZrO2 layer 3 with 1/2lambda- 1/8lambda thickness (normally 1/4lambda) and then the 2nd layer 4 with 1/4lambda thickness along with oxidization of SiO. The layer 4 contains not only SiO2 but nonoxidized SiO, SiO3 which is not perfectly oxidized, etc. Owing to this layer, the equal to or higher strength than a conventional film which is obtained through a surface reinforcement process is secured for this new reflection preventing film.
