The FOX2D CU 12_INF is primarily dedicated to SAXS or high resolution applications. Although, this 2D collimating mirror was originally designed for point sources, the temptation was high to install the optics in the reverse mode as synchrotron parallel beam concentrator. This test was recently performed at the Material Science beam-line of the Swiss Light Source (SLS, courtesy of Dr. Franz Pfeiffer) at 8 keV with promising results.

The FOX2D CU INF_12P focusing optics was placed in the collimated incoming beam to get a small focused spot (focusing distance =120 mm).
