X-ray focal image of the mirror shell 57 (approx. diameter 300 mm) measured at Al Kalpha (1.49 keV) with an half-energy-width of 8.2 arc seconds.

The mirror module qualification model (QM) for the European X-ray observatory XMM-Newton was tested in the PANTER X-ray test facility (Neuried) of the Max Planck Institute for Extraterrestrial Physics (Garching). The image demonstrates the quality of the module with an exposure of a 120 meter distant point source. The intrafocal and extrafocal images show structure due to the mirror shells and provide details for the residual structure of the image at the focal position.

Log-scaled intensity image of on-axis 8 keV Point Spread Function, as measured with the CCD camera supplied by the University of Leicester X-Ray Astronomy Group. The image covers approximately 10 x 6 arc minutes. The Half Encircled Energy radius is about 7 - 8 arc seconds.

This plot is a representation of how the XMM-Newton FM1 mirror module might focus a set of off-axis point source targets at field angles of 7 and 14 arc minutes approximately. Note that compared with ASCA, for example, the vastly improved angular resolution will allow better imaging, point source location, and a tremendous improvement in the ability to perform spectrophotometry in crowded fields.

Intensity plot (log-scaled) of a EUV (58 nm) image of the first flight model of an XMM-Newton mirror module obtained at Centre Spatial de Liege (CSL). The size of the image corresponds to one arc minute squared. The half energy width is 15.3 arc seconds and the 90% energy width is 60 arc seconds.
