This technique was first conceptualized and used on the Velociprobe x-ray microscope. The success of that design spurred adaption of the approach to over 90 devices, including many new instruments at the APS and high performing instruments at other synchrotrons. This paper details the design concept, some performance measurements, and new developments allowing for a six-degree-of-freedom device.
