Determination of Optical Constants of Fused Quartz by Attenuated Total Reflection Technique

Abstract

Optical constants of fused quartz are determined from the dispersion analysis of attenuated total reflection (ATR) spectrum in the frequency range 300 cm⁻¹ to 1600 cm⁻¹. The ATR spectrum has been fitted with the theoretical one obtained by using the dielectric constant of fused quartz that is expressed by an eight-oscillator model.
