| 摘 要： | 从像差理论出发,导出了消二级光谱的理论公式；根据公式对传统的两种用CaF2（萤石）与利用FK玻璃和TK玻璃组合消二级光谱色差方法和二元光学消二级光谱色差方法进行了实例计算,并用ZEMAX软件对它们验证、优化.两种方法都能在校正色差的基础上一定程度地减小二级光谱.对两者的结果进行对比分析发现,其二级光谱相异号,利用这一特点把两者结合在一起,能够更好地减小长焦系统中的二级光谱色差. |

| Abstract: | The formula of secondary spectrum was deduced founding on the aberration theory.Based on the formula,both the traditional way of using CaF2,using PK- TK and the way of Binary optics to eliminate secondary spectrum were calculated and optimized by ZEMAX.Both methods could decrease the secondary spectrum while chromatism had compensated well.Based on the counteracted characteristics of secondary spectrum between traditional achromats and binary optics,it can badly decrease by combining them together in the long focal optical systems. |
| Keywords: | Binary optics Secondary spectrum Abbe number Partial dispersion |
