N2 - We report an experimental demonstration of wavefront analysis via the Hartmann technique in the EUV. The reference wave front needed to calibrate the sensor was generated by spatially filtering a focused undulator beam with 1.7 (0.6) μm pinhole. To fully characterize the sensor, accuracy and sensitivity measurements were performed. The incident beam's wavelength was varied between 7 and 25 nm. Measurements of accuracy better than λEUV=120 (0.11 nm) were obtained λEUV=13.4 nm. The wavefront of the spatially unfiltered incident beam was also measured.
