怎么實現(xiàn)下面的光路：一個光束直接通過，在交界面上沒有反射；一個光束在交界面上折射90度。然后兩個光束合并在一起。 04l!:Tp,

你可以參考范例, \ZEMAX\Samples\Sequential\Optical testing\Twyman Green Interferometer \GZM&Zd  
希望對你有幫助

PBS   L-cos  專用喲！

什么意思呀？？？？？？

什么意思，不明白

謝謝a0010085提供的例子！但是要在第二個結構里設置相反的光束（就是兩個結構的光束對著來），怎么用命令？就是下面紅圈圈著的選框。我用的是非序列的！謝謝了！ N**g]T 0`  

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/ v}v 5

Hope this gives you a direction to look into :)
