Infrared filter：Infrared filters are generally cleaned by ultrasonic cleaners and centrifugal cleaners before coating. However, if ultraclean substrate surfaces are to be obtained, plasma cleaning is required to remove organic residues that are not visible to the naked eye. The material can also improve the coating quality and yield by using the plasma to activate and etch the substrate surface.
