Plastic optical element with gas barrier film, its manufacturing method and optical pickup device employing the element |
| abstract |
The present invention provides a plastic optical element with excellent durability and an optical pickup device with excellent pickup property. The plastic optical element is an plastic optical element with a gas barrier film comprising a resin substrate and provided thereon, at least one ceramic layer, the residual stress of the ceramic layer being from 0.01 to 100 MPa in terms of compression stress, and a density ratio Y (=ρf/ρb) satisfying the following inequality: n 1≧Y>0.95 wherein ρf represents a density of the ceramic layer, and ρb represents a density of a layer which has the same composition ratio as the ceramic layer and which has been formed by thermal oxidation or thermal nitridation of a metal which is a base material of the ceramic layer. |
