摘　　要：为了研究双透镜和球面镜之间不同球差分配对折反射式补偿器补偿效果的影响,以三级像差理论为基础,针对两个不同相对口径的凹抛物面镜,采用不同内部球差分配,分别设计了一组折反射式补偿器,将结果绘制成曲线.从曲线可看出,当球面镜球差分配系数从0逐渐增大到0.5时,对应折反射式补偿器补偿能力先增强,达到极值后下降.球面镜球差分配系数为零时,球面镜不承担球差,球面镜变成半径无穷大的平面镜,折反射式补偿器即变为Offner补偿器.研究表明,折反射式补偿器补偿能力强,但不同内部球差分配对补偿效果影响较大,合理选择球面镜球差分配系数对折反射式补偿器设计是有利的.In order to study the effct of different spherical aberration distribution between the double lens and single mirror on the compensation results of catadioptric compensator, based on the third-order aberration theory, aiming at two concave paraboloidal surfaces with different relative apertures, a set of catadioptirc compensators with different spherical aberration assignment were designed, and the curves of the design results were drawn. The curves indicate that ,when the spherical aberration bearing ratios of the single mirror increase from 0 to 0.5, the compensating ability of the catadioptric compensators rises fist, and begins to decrease after reaching the maximum. When the spherical aberration bearing ratio of the single mirror is O, it means that the single mirror will not help to the final compensation and the single mirror becomes a plane reflector, and the catadioptric compensator becomes an Offner compensator. The results show that, the compensating ability of catadioptric compensator is strong, the different distribution of spherical aberration bearing ratios has a great impact on the compensating results, and it is good to the catadioptric compensator design to choose a reasonable spherical aberration bearing ratio for the single mirror.
