"WebAn indication of the peak-to-valley flatness of a surface given in terms of waves (a multiple or part of a reference wavelength). For example, a specification of 1/4 wave means that the flatness of the surface deviates by one quarter of the wavelength used to test the surface. " - Peak to valley optics
