A comparative study of the performance of the Shack-Hartmann sensor (SHS) and interferometry in absolute sphericity tests was conducted. The absolute sphericity test was carried out with an existing TWG using the phase shifting technology. The same set-up and identical measurements were used to measure the wave fields in front of the SHS. For the SHS measurements, the reference arm of the TWG was obscured. The measured concave surface had a diameter of 40mm and a radius of curvature of 41mm. The used wavelength was λ=632.8nm and the distance of the contours in the plots is 0.050λ.
