Lensless Imaging with X-Ray Waveguides
A synchrotron generated X-Ray beam was coupled into an X-Ray waveguide located in the focus of Kirkpatrick-Baez mirrors . The resulting filtered wave was then used to illuminate a sample coherently , yielding a magnified hologram of the sample recorded by a pixel detector . Several linear positioners , goniometers , and rotators were applied for precision alignment of the waveguide with respect to the sample , which in turn was mounted on a high-precision tomographic rotation stage .

Special
Micro X-Ray Fluorescence Analysis ( micro-XRF ) Spectrometer
Confocal micro-XRF is a method to determine the spatial distribution of major , minor and trace elements within a sample in three dimensions . The employed polycapillary X-Ray optics need to be aligned precisely to get optimal results . Very compact positioners had to be used inside the vacuum chamber for this purpose . Long time stability of the alignment is also a major requisite . ANPxyz101 nanopositioners fulfill these requirements very well .
The figure to the left shows a 3D sample measurement of a cross made from 10 μm copper wire which is placed on an X-Ray screen and fixed using adhesive tape [ 1 ].
