最近关于偏振的问题比较多,整理了一些相关的信息,在这里作为一个分享。

先上两段说明书章节:
The Setup Tab > System Group (the Setup Tab) > System Explorer > Polarization (System Explorer) > What OpticStudio Can Compute Using Polarization Analysis > Limitations of Polarization Analysis
The Setup Tab > System Group (the Setup Tab) > System Explorer > Polarization (System Explorer) > Review of Polarization Concepts > Definition of Polarization Terms

然后强调一个关于偏振计算的细节,在进行计算的时候Z方向的分量会被丢掉,然后在x,y方向重新进行计算分配。

还有一点是,就是Jones矩阵是理想化的偏振矩阵,更加适用于小角度入射以及平行光线。
以下宏可以帮助进行偏振计算的理解。有问题可以留言,我搞不定会去找我们首席Michael问完告诉你。

Michael写了改良版的Jones Matrix,可以用于大角度光线入射。

关于上文提到的那个ZPL Macro,在下面的讨论当中有给出更多的解释,如果你跟我一样刚开始读macro比较吃力的话,可以看一下这段对话。

zemax里的偏振功能可以模拟pancake吗?模拟是否准确?

取决于你打算怎么用它模拟。上文有提到,Jones矩阵是理想化的偏振矩阵,更加适用于小角度入射以及平行光线。
