Soft X-ray multilayer polarizer

In the EUV region and soft X-ray region, where the refractive index of the material is close to 1, the Brewster's angle is around 45 degrees. Therefore, the multilayer mirror for use around 45 degrees has a high reflectance only for s-polarized light and also functions as a polarizer. Utilizing this characteristic, we offer multilayer film polarizers with sufficient efficiency from approximately 30 eV to 800 eV (1.5 nm - 40 nm).
These multilayer film polarizers are used not only for physical property experiments using synchrotron radiation and high-order harmonics, but also for basic research for industrial applications such as EUV lithography.
