[讨论交流] 全局优化中光阑放置位置的影响

1) If possible, place the stop on the first surface. If your entrance pupil is embedded in the system, you can model this by using a dummy first surface for the stop and then use a negative thickness to get to surface 2. This enhances performance because OpticStudio does not need to calculate where the entrance pupil is. You can make this thickness variable if appropriate. This technique does not work well for systems which inherently have entrance pupil distortion, such as wide angle lenses.

1）如果可能的话，将光阑放在第一面。如果你的入瞳在系统中间，你可以用一个虚构的第一面作为光阑，然后用一个负的厚度来得到表面2的方法来建模它。这提高了执行的性能，因为ZEMAX不需要去计算入瞳在哪里。如果合适的话，你可以把这个厚度作为一个变量。这个技巧不能很好地适用于本身有入瞳畸变的系统，如广角镜头。

       按照我的理解，是不是类似这样设计
