Polarization analyzer for vacuum ultraviolet and x-ray radiation

摘要

A polarization analyzer is disclosed which comprises a planar mirror mounted at an angle of incidence of 45 DEG with respect to the radiation on a mount which is rotatable about an axis parallel to the optical axis of the radiation. A detector is also provided which is pivotably mounted with respect to the mirror such that the detector is pivotable between a first position wherein the detector detects the radiation incident on the mirror and a second position wherein the detector detects the radiation reflected by the mirror.
