Abstract

The calibration way of a Shack-Hartmann sensor for the absolute wave front measurement of collimated beams is represented. Nearly perfect spherical wave fronts originating from a single mode fiber were used as references. After the calibration, the uncertainty of the wave front curvature is below 0.002 m^-1 over a diameter of 6 mm for the investigated sensor with a focal length of 27 mm. The procedure of the collimated beam preparation with the ultimate flat wave front over one millimeter for an atom interferometer is demonstrated.
