Transmission Fresnel zone plates and x-ray waveguides are presently the best high-resolution optical elements used in x-ray microscopy and micro-probing. The spatial resolution of zone plates is defined not only by the technological limit of about 10

Advances in the techniques of micro- and nano-fabrication mean that it is now possible to design and make microstructured optical arrays (MOAs). Due to greater flexibility in the choice of channel geometry and layout, these offer much better performa

The use of pupil plane phase masks provides a useful and efficient method of manipulating focal region light distributions. Such masks have found application in the telecommunication sector, including the use of Fourier plane replicating holograms fo

The first results using a scanning X-ray microscope, with zone plate optics, specifically designed for use with a laser-plasma X-ray source are reported. Unlike previous microscopes of this type, in which the specimens were mechanically scanned, in t

Characterization methods for grazing‐incidence reflecting channel arrays are discussed. Characterization of single‐reflection, unactuated micro‐structured optical arrays is required to evaluate their performance as focusing elements. Numerical

This paper describes two fabrication techniques-dry and wet etching- for microstructured optical arrays (MOAs). The MOAs consist of arrays of channels deep etched in silicon. They use grazing incidence reflection to focus the X-rays through the conse

This paper describes reflective adaptive/active optics for applications including studies of biological radiation damage. The optics work on the polycapillary principle, but use arrays of channels in thin silicon. For optimum performance the x-rays s
