We report the results obtained from the characterization of bent Silicon, Germanium and Gallium Arsenide crystals, which are being used for focusing photons in the 90-300 keV energy range, in the framework of the LAUE project. Such crystals represent the best choice for building Laue lenses thanks to their high reflectivity and to the narrow Point Spread Function (PSF) they can provide. The test aims to select the best material, to optimize the thickness and to estimate the curvature radius of the crystal tiles that will be used for building a 20 m focal length Laue lens petal.
