| 摘 要： | 讨论了一种新的双高斯型与Topogon型复合的光学系统。新型结构是在传统结构的基础上,于光阑附近增加一个光焦度不大的负薄透镜,降低了系统的高级负球差,减小量为-0.079 4,而增加的-0.110 7的高级负像散与初始设计的高级正像散抵消,并产生了-0.068 2的高级负场曲抵消原有的正场曲,使像散和场曲的校正得到明显改善,成像质量显著提高,特别是1视场MTF从0.112提高到0.493。

| Abstract: | Two designing results of a complex imaging object lens and its advanced design method are described. A thin lens with less power is added near the stop location in the advanced design,which can reduce 5th negative spherical aberration and give 5th negative astigmatic(-0.1107) to match the 5th positive astigmatic given by the former design.It also gives-0.0628 negative field curve.The astigmatic and field curve are obviously improved to get a better image,Especially,the value of MTF in 1 field is 0.493 in advanced design. |
