Wu Fan(Institute of Optics & Electronics, Chinese Academy of Sciences, Chengdu 610209)
According to third order spherical aberration theory, the calculation formulae of the compensation testing conicoid by using several technological spherical surface methods are deduced. On the basis of calculation results of these formulae, tracing ray is done. The compensation range of these formulae for convex conicoid is given and the plane analytic for- mulae under several special case are discussed.
