METHODS FOR ENHANCING DURABILITY AND MANUFACTURABILITY OF MULTILAYER INTERFERENCE MIRRORS

The invention discloses methods for enhancing the durability and manufacturability of multilayer interference mirrors. Specifically, a multilayer mirror, method, and ring layer gyroscope (RLG) are disclosed. For example, the method includes forming a plurality of layers of a first index of refraction optical material on a substrate, forming a plurality of layers of a second index of refraction optical material between the layers of the first index of refraction optical material, forming a layer of a durable optical material on an outermost layer of the plurality of layers of the first index ofrefraction optical material, and forming an over-coating of a protective material on a surface of the layer of the durable optical material. 本发明公开了增强多层干涉镜的耐用性和可制造性的方法。具体而言，公开了多层镜、方法和环形激光陀螺仪（RLG）。例如，该方法包括在基底上形成多个第一折射率光学材料层，在所述第一折射率光学材料层之间形成多个第二折射率光学材料层，在所述多个第一折射率光学材料层的最外层上形成耐用光学材料层，和在所述耐用光学材料层的表面上形成保护性材料外涂层。
