Optical component and method manufacturing the same |
摘要 |
The optical component includes a substrate made of a resin material, a silicon oxide film formed on a surface of the substrate, and a multilayer light reflection preventing film formed on the silicon oxide film, and having at least one layer of a low-refractive-index material and at least one layer of a high-refractive-index material being alternately formed. The silicon oxide film is thick and/or formed by introducing oxygen during film forming by vacuum deposition so that a preset elasticity is imparted to the silicon oxide film. Other optical component includes a substrate made of a resin material and a plurality of films formed by vacuum deposition, and directions of internal stresses in each adjacent pair of the plurality of films are different from each other or a thickness of an impurity existing on a surface of the substrate is 0.2 nm or less. The plurality of films are formed by performing melting of film forming materials other than a film forming material for a film formed on the surface of the substrate after the film is formed on the surface of the substrate.
