我今天在使用软件的时候，遇到了一个问题，在函数编辑器里设定目标的时候PBS的时候只有Rs,Rp, 没有Ts,Tp，还是Ts,Tp是可以自定义的，

If I understood you correctly, you're missing Ts/Tp inputs in Beamsplitter preset?
True, it doesn't let you set them, but it does generate Ts, Tp targets for you. They are set as Ts=1-Rs and Tp=1-Rp, which is true as long as there is no absorption (materials have k=0).
RGT is continuous target over range for R, TGT is same for T.
Note that in total mode the substrate is included, so BK7 absorbs a bit in the band and Tp=100% won't be reached exactly. That's fine for optimization, MF just won't go to zero.

What you can do:
Use Custom target. That way you can generate target for Tp=100 and separately for Rs=100.

Also noticed that I forgot to remove this dropdown for polarization, it does nothing with beamsplitter preset selected fyi. I'll fix this in the next patch.

非常感谢。

@xluo3166-pixel Also you can draw targets on optical evaluation plot directly (only for 0 deg now)

好的我试试，非常感谢。
