Abstract
An optics system component has a stainable glass substrate, an optical coating comprising alternating layers of dielectric materials, and a buffer layer positioned on the stainable glass substrate between the substrate and the optical coating. The buffer layer comprises a dielectric material and has a thickness of less than about 20 nm.
Claims14
A method of forming an optical system component, comprising the steps of:
- providing a glass substrate comprising one or more fluorides, the glass substrate having a thermal damage threshold;
- depositing a first portion of a first layer of an optical coating via plasma deposition on the glass substrate at a first plasma bias voltage;
- depositing a second portion of the first layer of the optical coating via plasma deposition on the first portion at a second plasma bias voltage, wherein the second plasma bias voltage is greater than the first plasma bias voltage;
- and
- depositing a second layer of the optical coating on the first layer.
