OPTICAL COMPONENT AND MANUFACTURING METHOD THEREOF

摘要

An optical component includes a multilayered optical thin film formed on a substrate. A critical load value of the optical thin film that includes at least one layer that is formed by a vacuum deposition method is greater than or equal to 30 mN. The critical load value is a value evaluated by a measurement method complying with JIS R3255“Testing methods for adhesion of thin films on a glass substrate”.
