Astronomical Telescopes + Instrumentation, 2018 X-ray astronomy critically depends on X-ray optics. The capability of an X-ray telescope is largely determined by the point-spread function (PSF) and the photon-collection area of its mirrors, the same as telescopes in other wavelength bands.

Multislice does it all-calculating the performance of nanofocusing X-ray optics.
Optics Express, 2017 We describe an approach to calculating the optical performance of a wide range of nanofocusing X-ray optics using multislice scalar wave propagation with a complex X-ray refractive index. This approach produces results indistinguishable from methods such

X-ray Focusing and Optics [PDF]
, 2020 AbstractThis chapter addresses fundamental concepts of X-ray optics and X-ray coherence, in view of the increasing number of X-ray applications requiring nano-focused X-ray beams. The chapter is meant as a tutorial to facilitate the understanding of later chapters of this book.

Adaptable refractive correctors for x-ray optics
, 2019 Advances in x-radiation sources put greater demands on x-ray optics. Fabrication errors in optical elements lead to deformation of the radiation wavefront, which prevents diffraction-limited imaging of the source.

Graphite Optics—Current Opportunities, Properties and Limits
Condensed Matter, 2019 X-ray graphite optics consists of thin layers of Pyrolytic Graphite (PG) attached to a substrate of focusing shape. Pyrolytic Graphite is a perfect artificial graphite obtained by annealing of carbon deposit at temperatures about 3000 °C under ...

Multilayer X-ray optics at CHESS [PDF]
Journal of Synchrotron Radiation, 2006 Almost half of the X-ray beamlines at the Cornell High Energy Synchrotron Source (CHESS) are based on multilayer optics. ;Traditional' multilayers with an energy resolution of DeltaE/E approximately 2% are routinely used to deliver X-ray flux enhanced by a factor of 10(2) in comparison with standard Si(111) optics.

Correct interpretation of diffraction properties of quartz crystals for X-ray optics applications
, 2018 Quartz has hundreds of strong Bragg reflections that may offer a great number of choices for making fixed-angle X-ray analyzers and polarizers at virtually any hard X-ray energies with selectable resolution.

Optics for coherent X-ray applications [PDF]
Journal of Synchrotron Radiation, 2014 Developments of X-ray optics for full utilization of diffraction-limited storage rings (DLSRs) are presented. The expected performance of DLSRs is introduced using the design parameters of SPring-8 II. To develop optical elements applicable to manipulation of coherent X-rays, advanced technologies on precise processing and metrology were invented. With
