Title: The Optical Constants of Lead Sulphide, Lead Selenide and Lead Telluride in the 0.5-3 Region of the Spectrum
Abstract: Measurements have been made of the refractive and absorption indices n, k of PbS, PbSe and PbTe at wavelengths between 0.5 and 3 μ, using a reflection method. The values found for n at 3 μ are for PbS 4.10, PbSe 4.59 and for PbTe 5.35. The absorption spectra found agree with earlier work, and it has been shown that for PbS a variation of 200: 1 in the concentration of impurity centres in specimens produced no change in the magnitude of the absorption.
