Asphericity which affects the manufacturing process and the grinding quantity is an important parameter of optical aspherics. In this paper  the approximation  the least square fitting  wavefront aberration  sag methods are given for the calculation of optical asphericity. The effects of different definitions of optical asphericity are analysed to optimize the process of manufacture. A sag method is presented to solve the best-fit sphere and asphericity for an off-aixs aspheric mirror with a rectangle aperture of 180mm145mm  and polishing quantity and distribution plots are given. The optical manufacturing and testing technology for different choices of best-fit spheres and asphericity are described and analyzed. Therefore  proper definition of optical asphericity which is useful to manufacturing is very important for optical fabrication and test. 2009 SPIE.
