This paper deals with the two-dimensional Hartmann quantitative test of the largest hyperboloidal primary mirror made in China. It is the first of its kind carried out in this country. It provides geometrical energy concentration, spot diagram at best focus, contour map for the mirror and aberration coefficients of Zernike polynomial fitting wavefront. In addition, parameters of the real shape, i.e., real radius of its curvature (R) and function of eccentricity of a conic surface (e2) are given.
