Abstract Precise knowledge of the incident and diffracted X-ray beams related to flat crystal diffractors is important for X-ray diffraction optics and for high resolution experiments. In the paper, three-dimensional reciprocal space concept has been applied to study general case of the flat diffractor. The incident and diffracted beams have been determined for the middle of the range of total reflection for both the standard asymmetrical and the inclined asymmetrical diffractor. For an asymmetric diffractor rotating about its reciprocal lattice vector unexpectedly large out-of-plane-of-diffraction components of the beams have been obtained. The largest ones have been found not for the angle of rotation ω = 90° corresponding to a symmetrical inclined diffractor but for the angle close to the grazing incidence case.
