A possible design for a spherical grating monochromator is based on the translation of the entrance slit in order to minimize the system aberrations during the wavelength scan. This configuration has been studied both analytically and by means of extended ray-tracing calculations and the design and performance of such a monochromator are discussed. In order to verify advantages and limitations of this solution a systematic comparison with a spherical grating monochromator with a moveable exit slit has been performed.
