Influence of figure error and VLS miscut on resolution. (a, c) Analytically estimated resolution of the monochromator operating in first diffraction order with designed and installed 50 l mm−1 gratings; slope error on premirror 50 nrad RMS. (b) Instrument response function of the 500 mm-long 50 l mm−1 designed grating operating in first diffraction order at 1.5 keV obtained by wavefront propagation simulations for the cases of different magnitudes of slope error on the grating. (d) Analytically estimated tolerances on the VLS b2 parameter for the 500 mm-long 50 l mm−1 designed grating and for the 120 mm-long 50 l mm−1 grating.
