Zirconium and Niobium Transmission Data at Wavelengths from 11-16 nm and 200-1200 nm
Transmission measurements of niobium and zirconium at both extreme-ultraviolet (EUV) and ultraviolet, visible, and near infrared (UV/Vis/NIR) wavelengths are presented. Thin foils of various thicknesses mounted on nickel mesh substrates were measured, and these data were used to calculate the optical constants {delta} and {beta} of the complex refractive index n = 1- {delta} +i{beta}. {beta} values were calculated directly from the measured transmittance of the foils after normalizing for the nickel mesh. The average {beta} values for each set of foils are presented as a function of wavelength. The real (dispersive) part of the refractive index, {delta} was then calculated from Kramers-Kronig analysis by combining these {beta} values with those from previous experimental data and the atomic tables.
