复消色物镜的波差法光学设计

Optical design of apochromatic objective with wave disparity method

采用波差法进行复消色物镜的光学设计。以球差与波差、色差与波色差的关系为基础,推导出了波差与结构参数之间的关系方程式。运用得到的方程式来计算初始结构,可以充分发挥用计算机编程处理复杂问题的优势,使复杂的计算问题能够快速解决。针对光学设计中的两大难点之一——复消色大口径长焦距平行光管物镜的设计,利用自行编写的光学设计程序,采用低价的国产玻璃成功地设计出高质量的复消色大口径长焦距平行光管物镜。同理,选取不同的玻璃组合,也能设计出高质量的复消色摄影物镜。最后给出多个设计实例对采用的设计方法进行了验证,结果表明,采用波差法进行复消色物镜的光学设计简单易行,且设计的物镜质量高,成本低。

Optical design of apochromatic objective used wave disparity method in this paper. Based on the relationships between spherical aberration and wave disparity, color aberration and wave front chromatic aberration, the equations of structure parameter and wave disparity are deduced. By use of the equations to get the original structure, which take advantage of the computer dealing with the complex questions, and make the questions easily to be solved. Apochromatic objective design of long focus collimator is one of the two key problems of optical design. According to the program of optical design, we use the glasses that made in china to design some high quality apochromatic objectives of long focus collimator. In the same way, we can design the apochromatic photograph objective by different glasses. In this paper, we give some examples in order to validate the method of optical design. The result indicates that the method is simple, and the optical design of apochromatic objective is high quality, and the cost is cheap.
