Light scattering and Atomic Force Microscopy (AFM) are used together to analyze surface roughness in a very wide frequency bandwidth, extending from macroscopic (optical) to microscopic (AFM) scales. The two techniques are shown to be in large agreement since the roughness spectra overlap at intersection of bandwidths. A particular behavior of roughness is emphasized that permits to predict scattering at very short wavelengths. Thin film materials obtained by different techniques (IAD, Ion Plating, EB) are also investigated via a comparison of roughness spectra measured before and after coating in all bandwidths.
