A first measurement with a stitched G1-grating manufactured at KIT/IMT was carried out at TU Munich. In setups for phase contrast imaging three gratings

are needed. They are named G0, G1 and G2 after their position along the setup. For the first time measurements with a stitched G1-phase-grating were performed to compare with measurements with a non-stitched grating. Here a G1-grating stitched from 2 x 2 pieces was compared with a single laser written G1-grating.
