Zusammenfassung: An overview of the current status of the state of art in angle metrology is provided by giving update information on the Joint Research Project (JRP) SIB58 'Angles' of the European Metrology Research Programme (EMRP). Current and future challenges to angle metrology are described presenting the requirements on the quality control of ultra-precise X-ray optical components for application in the Synchrotron Radiation (SR). Investigations performed on autocollimators for the first time under extremely challenging measuring conditions (performance with variable path lengths, with two axis operation, at small apertures, on curved surfaces, with aperture positioning relative to autocollimator axis), development of novel methods for determination of error sources in angle encoders and small angle generators to provide traceability with expanded uncertainties of less than 0.01" (50 nrad) are reported with the first results in addition to the highlights from the work carried out in the JRP.
