The method is argued in the paper which is used to obtain dioptrie and radius of lens of optical system on the apparatus of artificial star by wave aberration. In order to correct secondary spectrum and distortion, equal position chromatism and equal spherical aberration are retained in front and raer group in the long focu system, and the values of front is minus in positive optical path and raer plus in opposite. Results required can be accurately obtained by wave aberration.
