X-ray optics are notoriously challenging to fabricate due to the strict tolerances that result from the short wavelength of radiation. Here, Seibothet al. carefully quantify aberrations in complex X-ray lenses and correct them with an easy-to-fabrica

We demonstrate how the optical transmission by a directly illuminated, sub-wavelength slit in a metal film can be dynamically controlled by varying the incident beam's phase relative to that of a stream of surface plasmon polaritions which are genera

Due to their short wavelength, X-rays can in principle be focused down to a few nanometres and below. At the same time, it is this short wavelength that puts stringent requirements on

We present a nanofabrication process for producing tungsten zone plates used in hard X-ray applications including a method of integrating a high-energy absorbing central stop with the optic. Tungsten zone plates are structured with electron-beam lith

Most biomedical applications are based on the light–matter interaction; the measurement of absorption, scattering or fluorescence at the visible and near visible region of the electromagnetic spectrum. This can be enhanced with nanophotonical devic

I13 is a 250 m long hard x-ray beamline (6 keV to 35 keV) at the Diamond Light Source. The beamline comprises of two independent experimental endstations: one for imaging in direct space using x-ray microscopy and one for imaging in reciprocal space

A Ronchi interferometer for hard X-rays is reported in order to characterize the performance of the nanofocusing optics as well as the beamline stability. Characteristic interference fringes yield qualitative data on present aberrations in the optics
