标题: 求助！为什么ASAP模拟结果和Zemax设计结果很不一样？

我用Zemax设计了一个系统，作用是把平行光聚焦到像面上，为什么用ASAP7.5模拟后发现光线根本没有被追迹?结果和设计结果也不一样？请高手指点！！！
下面是ASAP7.5的编程语句.

第115行应该是 TRACE PLOT

哦！十分感谢！！！！！！！！

1）把材质名称“H-K9L”改为：“K9L”，因为它会把“-”当作减号运算符来处理。
2）你把LENS2.BACK及LENS3.FRONT的材质写错了，前者应该是K9L  AIR而不是K9L ZF2，后者应该是ZF2 AIR而不是K9L ZF2 。
3）下面是我修改后的程序，有些小问题的地方我没有写出来，你可以仔细看看。当然，有些地方可能我也是错的，也希望你能帮我指出。大家相互学习，共同进步嘛。呵呵。谢谢啊！

呵呵，十分感谢！！！！
不过，我的第二块和第三块之间是胶合面啊！怎么设置阿！

作者: 121331768 时间: 2008-12-27 16:11

呵呵，找到问题点了，是因为我不小心把曲率半径输入错误了！！呵呵，见笑了!!

如果是胶合镜片的话，那么胶合面只需要建一个面就可以了，不用两个面都建

哦。回去试一下，是什么命令啊？
