The design process for these polarization optics, so-called k-mirrors, in the EUV wavelength range is explained with possible design extensions for other wavelengths. These polarization optics in EUV are extended with full-beam polarimetry of harmonic light generated with structured illumination. Characterization of the fundamental light’s structured illumination and polarization profile combined with similar characterization of the harmonics can reveal insights into the HHG process.
