Abstract
Focusing properties of a Wolter mirror were evaluated in a hard X-ray region (∼10 keV). Although the sagittal focal spot size was found to be 0.7 μm, some spots are spread in meridional direction within a range of over 100 μm. A Foucault-test method has been employed for closer investigation of the focusing properties. Wave-front of the sagittal focusing rays was almost ideal. On the contrary, it was found that slope error of about 100–300 μrad existed for the meridional focusing.
