The concept of a focusing monochromator with high energy resolution is presented. Different from conventional optical schemes, the device exploits not the angular but the spatial dispersion of synchrotron radiation. The wave theory of the monochromator is developed; it shows that the monochromator can reach an energy resolution of about 0.1 meV without significant loss of the spectral density of synchrotron radiation.
