  Advanced Optics, Inc.
  Resurfacing Optical flats

  Optical flats and windows become worn and abraded in use and accuracy is lost. This degradation in performance is due to a decrease in the distinctness of the interference pattern, and to a change in the figure caused by scratches on either side of the flat or window. Repolishing the surface of a piece back to its original accuracy can be less costly than replacement. Advanced Optics maintains an optical flat refinishing service with fast turn-around time.
