Dynamical Laue-diffraction of X-rays on the bent crystal is presented. The phase of diffracted wave takes into account cubic terms. The DuMond-type spectrometer is considered for the X-ray source, situated on the Rowland-circle. Dynamical theory of the DuMond-type spectrometer is developed for ideal and mosaic curved crystals. Dependence of the spectral resolution on the source dimensions is analyzed.
