Abstract

Contours of constant principal angle Φ and constant principal azimuth Ψ for an in-line, symmetric, three-reflection mirror system are presented. The three mirrors are assumed to be uncoated substrates of the same homogeneous isotropic material with complex relative dielectric function ε. By assigning values to Φ from 45 to 85 deg in 5-deg steps, the constraint on complex ε is determined numerically and represented graphically. The special case of Φ = 45 deg, which applies to a right-angle parallel-mirror beam displacer, enables an analytical solution. These results have important applications for the production of circular polarization over the entire spectrum, and especially in the VUV, where transmission-type devices are not possible. The performance of the three-mirror system as a VUV quarter-wave retarder/circular polarizer using different metals is also considered.
