Abstract: | A non-coaxial grazing X-ray microscope, consisting of four spherical mirrors, is designed for diagnosis of inertial confinement
fusion (ICF). The aberrations and imaging quality of the microscope are analyzed. To acquire excellent imaging quality, suitable
tolerances for manufacturing and assembling the microscope are necessary. This paper researches the changes of Gauss parameters
and aberrations due to component and subsystem parameters (such as the radius of the mirror, angle between mirrors, grazing
angle, object distance, etc.). Here, spot diagrams and modulation transfer function (MTF) are first adopted to quantitatively
evaluate the imaging quality of the microscope. Suitable manufacturing tolerances of components and assembly tolerances of
the system are established on the basis of the discussion and analysis. A set of non-coaxial grazing X-ray microscopes is
manufactured based on the tolerances. In site tests of ICF, the images with high resolution are obtained by the microscope.
