The brilliance of undulator X‐ray sources can be used to develop microfocusing optics for wide‐angle (WAXS) and small‐angle (SAXS) X‐ray scattering. At the ESRF microfocus beamline, a beam size of 10 μm is obtained by a pinhole collimating system coupled to a double focusing mirror. This allows resolving the first order of collagen (67 nm). Glass capillary optics provides a beam size close to one micron, however, with a more limited resolution. A high‐resolution CCD detector allows combined SAXS/WAXS experiments for one detector setting.
