Abstract:
1. A method comprising: providing a multi-layer interference system that has been removed from a deposition chamber, the multi-layer interference system comprising a stack of optical thin film layers and a supporting member, the stack comprising a plurality of high index optical thin film layers interleaved with a plurality of low index optical thin film layers; determining whether an optical parameter of the removed multi-layer interference system fails to comply with an optical specification; responsive to a determination that an optical parameter of the removed multi-layer interference system fails to comply with an optical specification, continuously treating the removed multi-layer interference system with light; monitoring a response of the removed multi-layer interface system to the light; predicting a performance of the optical parameter following treatment with the light based on the monitoring; responsive to a determination that the predicted performance of the optical parameter complies the optical specification, stopping the light treatment and testing the optical performance of the optical parameter; and responsive to a determination that the tested optical performance of the optical parameter is acceptable, accelerating an aging of the removed multi-layer interface system.
