## Abstract The optical properties in terms of dielectric function __ϵ__ (__ħω__) = __ϵ__~1~(__ħω__) + __iϵ__~2~(__ħω__) of rocksalt Pb~1–__x__~ Sn__~x~__ Te alloys (0 ≤ __x__ ≤ 1) are investigated experimentally by spectroscopic ellipsometry and theoretically by first‐principles electronic band st
