A leaf spring bender geometry for water-cooled double Laue crystal monochromator (DLM) is presented. The DLM will be employed to acquire high energy mono-chromatic X-ray (60keV to 120keV) on the ultra-hard applications beamline at SSRF. A compact bending mechanism is designed in order to get horizontally fo-cused high energy monochromatic X-ray as small as 0.5mm. The bender applies a piece of thin asymmetric crystal and a pair of leaf springs which push the crystal to a sagittally bent radius as small as 1 meter by a pair of symmetry moments. An optimized crystal geometry is achieved by taking into account the meridional and sagit-tal bendings coupled and defined by the anisotropic elas-ticity of the asymmetric crystal. Furthermore, thermal slope error and structural stress of the bent crystal are analyzed by finite element method (FEA).
