Paper Abstract

Relative measuring errors of optical constants calculated from modified Kramers-Kronig relations are estimated for steel and gold surfaces having rms roughness 0.01 μm, 0.02μm, and 0.03μm. Spectral distributions of intensity reflectance used for the calculations are given for two spectral ranges of 0.14-6.4 eV and 1.4-6.4 eV. It is found the measuring errors slightly depend on the spectral range variations and the main contribution to these errors is brought by the surface roughness.
