RESURFACING OPTICAL FLATS
Optical flats and windows become worn and abraded over use, losing accuracy. 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. Re-polishing 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 a fast turnaround time.
