[求助]怎么在zemax里面实现这个光路-偏振合束器？ [复制链接]

怎么实现下面的光路：一个光束直接通过，在交界面上没有反射；一个光束在交界面上折射90度。然后两个光束合并在一起。 $u4esg

你可以参考范例, \ZEMAX\Samples\Sequential\Optical testing\Twyman Green Interferometer V]PTAhc  
希望对你有帮助

PBS   L-cos  专用哟！

什么意思呀？？？？？？

什么意思，不明白

谢谢a0010085提供的例子！但是要在第二个结构里设置相反的光束（就是两个结构的光束对着来），怎么用命令？就是下面红圈圈着的选框。我用的是非序列的！谢谢了！ ))F.|w  

我知道了！！！

you could make use of coating to allow one ray path totally transmitted at a given indicent angle and the other tottaly reflected with respect to the incident angle ....

I couldn't find this coating. Is this available in Zemax? Or I need create it by myself? Please give me more guide to do it.

take a look of the "TABLE COATING" under the user manual. There is no single coating can allow total tranmssion as well total reflection at the same time at a "single wavelength" at the same incident angle with respect to the incident surface. If it is something simple like a 50:50 tranmission/relfectio situation, you could simply used "I." type of coating. If the beam no 1 and no 2 are at differernt wavelngths then you could make use of "Table Coating", so you can then define the transmission/refelction at a given wavelength as well as incident angle. There are some examples privided in ZEMAX as well as in the user manual/ EcoUpiL%2

Hope this gives you a direction to look into :)
