Optical Filter Reliability Testing
The complexity of optical coating manufacturing has encouraged a dependence upon well controlled processes to insure constant and consistent optical filter product output. True control of processes depends upon assessment of the process output and appropriate adjustment of the process when results indicate a deviation from desirable /expected results. Reliability testing provides the statistical data necessary to monitor and control process variables which can contribute to product durability and ultimate lifetime.Reliability testing is the only valid method of verifying whether a product meets all of its specified requirements at the time of manufacture and whether it is likely to achieve the useful lifetime for which it was designed and manufactured.Data produced from reliability testing also provides the necessary information to allow statistically based product capability assessments to be made relative to customer specified lifetime requirements.
