Abstract

Two optics damage inspection system will be implemented on the NIF, one to inspect optics within the laser and transport sections and the other to inspect the final optics at the target chamber. Both system use dark-field imaging technology to enhance defect contrast. Details of each system design will be provided. A functional optics damage inspection system prototype, using dark-field imaging technology, is currently in operation on the Beamlet laser. This system provides us with the opportunity to measure non- ideal optical surfaces expected to be present on NIF. Prototpye details and performance will be presented.
