The system efficiency is the fraction of the energy in the source b53s@7/mq
beam that exits the optical system. This value is determined by w~=xO_%
the input na, entrance pupil size and position, apodization, |S<!' rY
transmission of the optics, and vignetting. U(OkTJxv+

数值孔径不是越大越好呀,当耦合光学系统的模式与你光线的模式完全匹配时,耦合效率最大. bcxR7<T,"9
耦合效率的计算有一个积分过程,还是比较复杂的.
