25、习了一周,但在软件真正上手时需要的时间却是大半个月。对于 zemax 软件设计的方法和问题总结如下:1、设计过程:找初始结构,我在找的过程中是以焦距相近为目标的,不知道是否合理;依次修改入瞳直径、视场、波长,生成焦距,再修改入瞳直径;建立评价优化函数,输入焦距函数,对各个目标设定合理权重;优化和锤形优化,修改玻璃库,将贵重材料去除;生成报告。2、对于大口径的设计,需要仔细的调试,综合考虑各种初级、高级象差。我一开始找了四种初始结构:单双物镜,双单透镜,对称式物镜,以及报告中的两个单透镜和一个三胶合透镜。通过对默认函数的建立对比象差(点列图、垂轴色差、场曲/畸变)选出了所用的结构。然后对其精细设计。3、对于小口径的物镜,不需要考虑高级象差,设计比较方便,只需用双胶合透镜方便消色差即可。4、对于自建的优化函数,虽然象差容限已知,但象差肯定越小越好,但修改象差权重同时另一个就变大了,因此需要知道各个象差所占的比重,哪些象差比较重要,哪些应优先适当小。
