Title:
OPTICAL ELEMENT AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2020/184727
Kind Code:
A1
Abstract:
The present invention provides a method for producing an optical element which comprises a base material and a multilayer covering film that is formed on the base material. A production method according to the present disclosure comprises a multilayer formation step for forming an optical multilayer part of the multilayer covering film and an outermost surface formation step for forming the outermost surface part of the multilayer covering film; and the pressure conditions for forming the multilayer covering film are not continuous between the multilayer formation step and the outermost surface formation step. In addition, a layer containing silicon oxide is formed before the formation of a layer containing a fluorine compound in the outermost surface formation step.
