Reflective x-ray optics

WebUsing soft X-rays with a wavelength of 13 nm, a diffraction limited projection system with an NA of about 0.09 would have a resolution of about 0.1 μm. The corresponding Rayleigh depth of focus would be about 1.6 μm. Several catoptric reduction designs for use in this regime have been proposed, but they are limited to very small field sizes, because of the … Web1. sep 2024 · On two of the modules, the ring interfaces the mirror module to a Reflection Grating Assembly (RGA). To minimise the mechanical deformation of the mirrors and therefore the optical degradation, the flatness of the interface between the spider and the MIS had to be better than 5 micron. X-ray baffles are located in front of the mirror systems.

The mirrors can be made of glass, ceramic, or metal foil, coated by a reflective layer. The most commonly used reflective materials for X-ray mirrors are gold and iridium. Even with these the critical reflection angle is energy dependent. For gold at 1 keV, the critical reflection angle is 2.4°. The use of X-ray mirrors simultaneously requires: • the ability to determine the location of the arrival of an X-ray photon in two dimensions, WebA mirror that transmits a percentage of incoming light.
