The efficiency η L C of linear-to-circular polarization conversion when light is reflected at a dielectric–conductor interface is determined as a function of the principal angle ϕ ¯ and principal azimuth ψ ¯ . Constant- η L C contours are presented in the ϕ ¯ , ψ ¯ plane for values of η L C from 0.5 to 1.0 in steps of 0.05, and the corresponding contours in the complex plane of the relative dielectric function ϵ are also determined. As specific examples, efficiencies 88 % are obtained for light reflection by a Ag mirror in the visible and near-IR ( 400 1200 nm ) spectral range, and 40 % for the reflection of extreme ultraviolet (EUV) and soft x-ray radiation by a SiC mirror in the 60 120 nm wavelength range.
