X-ray microscopy can be used in many research fields for imaging applications with resolutions notable below 100nm, continuously pushing the limits to near diffraction limited resolutions.

AnImaX (Analytical Imaging with X-rays) is a flexible endstation for combining scanning and full field microscopy using synchrotron radiation in the soft X-ray spectral range. The AnImaX platform consists out of up to three separate vacuum chambers and custom designed high resolution piezo driven stages. The AnImaX endstation has been successfully put to work at the beamline P04 at PETRA III.

The use of a spatial resolved detector in scanning mode allows the simultaneous acquisition of different imaging modes by adjusting the detector response function. The CCD based multimodal detector system allows beside absorption contrast the acquisition of phase contrast and dark field images. The obtained diffraction patterns can also be used for ptychography. In the scanning mode the SDD detector with its outstanding solid angle of detection also gathers a fluorescence spectrum for each pixel. Thereby a detailed spatial elemental and chemical analysis of the specimen is performed.
