This paper describes a new monochromator design for a bending magnet beamline of the Swiss Light Source synchrotron facility. The beamline optics is based on a horizontally deflecting spherical grating monochromator (SGM) with two gratings at a constant deviation angle. It covers a photon energy range from 200 eV to 1000 eV. This paper concentrates on the original flexure-based mechanisms with partially parallel kinematics invented and designed for this monochromator, as well as on the lessons learned from the assembly and testing of the system.
