Abstract

The optical responses of two sides of float glass in the soft-x-ray region were studied at the Indus-1 synchrotron facility. To the best of our knowledge these are the first experimentally obtained optical data for both sides of float glass in the soft-x-ray region. Optical constants δ and β were determined by use of angle-dependent reflectance techniques in the wavelength range 80–200 Å. On the side of the glass that was tin indiffused, a significant difference in δ value from that of the non-tin-side surface was observed. The measured data were compared with Henke’s tabulated value of SiO<sub>2</sub>. The surface roughness of float glass was separately determined by hard-x-ray reflectivity to minimize the number of fitting variables. The effect of a contamination layer on the determination of optical constants was avoided by an appropriate sample-cleaning method.
