High angular resolution slope measuring deflectometry for the characterization of ultra precise reflective x ray optics

Slope measuring deflectometry has become a standard technique for inspection of ultra precise reflective optical elements of synchrotron applications. We will report on the inspection of ultra precise adaptive synchrotron mirrors bimorph mirrors to be used under grazing incidence condition. The measurements were performed at the BESSY II Optics Laboratory of the Helmholtz Zentrum Berlin using the nanometer optical component measuring machine NOM . Based on the data obtained by the optical measurements, we in this paper simulate the characteristics of the achievable x ray focus by ray tracing calculations, demonstrated in the case of bimorph mirrors of the EMBL MX1 beamline for macromolecular crystallography at DESY s synchrotron radiation source PETRA III in Hambur
