Two-Dimensional Quantitative Hartmann Test of the 1.2m Primary Mirror and the 1.2m Telescope

The two-dimensional quantitative Hartmann tests lor the 1.2m aspherical primary mirror and the 1.2m alt-azimuth telescope at the Yunnan Observatory are performed. For the Hartmann test of the 1.2m primary mirror, the optimum choice of the geometrical parameters of the Hartmann screen is made. The light energy concetration, the distribution of the spot diagram at the optimum focal plane of the 1.2m primary mirror and the 1.2m telescope and the surface deviation distribution of the 1.2m primary mirror are obtained.
