請問一下，我在zemax物理光學(xué)傳播（physical opticals propagation 里看到了以total power的量，這個量代表的是光束的能量嗎 N UvVhy]{

Under POP propagation you will see Beam Definition, under this tab you can define either the "Total Power" of the beam or the "Peak Irradiance". So the total power returns under the window (as you captured) will be reporting the total power with respect to the energy defined under this "Beam Definition". +or<(%o @

選擇total power 和 peak irradiance會有什么不同呢，還有我想改變鏡子大小來看光的通過率，設(shè)定選擇surface type里的 aperture type 里的通光孔徑的大小，再看total power 的大小，這樣是不是可以說明不同半徑下光的通過率啊。
