【 摘 要 】

A diffraction component of angular resolution of spherical Q2131 and Ge422 crystals was calculated, measured in experiment and the good agreement was found. Simulation of geometrical component of angular resolution of bent crystals was also performed and the code is designed to simulate reflectivity of the concave crystals. Such code is also aimed to estimate the resolution of focusing x-ray spectrometers.
