Effects Of Long -Term Ion Bombardment On Some Optical Properties Of Rh Film Mirrors And Bulk Polycrystalline Mirrors

The method is suggested for statistical analyzing the surface structure in cases when the spatial size of structure is not negligibly small in comparison with the size of an area to be analyzed. The method is applied to Rh film mirrors subjected to sputtering by ions of deuterium plasma. The r.m.s. heights quantities are defined from STM and from reflectance in the range 250...650 nm. The irregularities height distributions and the spatial length spectra are studied. The data are compared with those for bulk Cu, SS and Mo polycrystalline mirrors tested in similar conditions.
