Abstract
Lead sulfide (PbS) in thin film form was prepared by thermal evaporation in order to evaluate its optical characteristics. The absorption coefficient of lead sulfide in the 3-11 microns band of the infrared spectrum was calculated under smooth and rough surface conditions. The calculated and measured absorption coefficient was in a good agreement with that published by Semiletov. These results were an order of magnitude higher than that published in the handbook of optical constants of solids and referred to Scanlon
