Abstract
We present the development of a soft X-ray Foucault test capable of ch aracterizing the imaging properties of a soft X-ray optical system at its operational wavelength and its operational configuration. This opt ical test enables direct visual inspection of imaging aberrations and provides real-time feedback for the alignment of high resolution soft X-ray optical systems. A first application of this optical test was ca rried out on a Mo-Si multilayer-coated Schwarzschild objective as part of the MAXIMUM project. Results from the alignment procedure are pres ented as well as the possibility for testing in the hard X-ray regime.
