摘　　要：　通过移动变倍组和补偿组,在保证所要求的变焦倍率的同时,考虑高级像差对最佳像面的影响,调整各组之间的间隔,使之尽量符合各焦距最佳像面的位移变化,最终达到在各种焦距位置时对高斯像面的严格一致。Under the condition of holding variable power, with the movement of compensating lens group and multifocal lens group, considering the influence of highgrade aberration on optimum position of image, adjusting the space length between all lens groups, making the space suitable for displacement of optimum position of image plane of every focal length, the Gauss image plane would be finally in accordance with every focal length.

关 键 词：最佳像面 变倍组 补偿组 像差
