The system efficiency is the fraction of the energy in the source sPE)m_u
beam that exits the optical system. This value is determined by 1^60I#Vr@
the input na, entrance pupil size and position, apodization, yS uLt@X
transmission of the optics, and vignetting. fs3 -rXoB

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. $&xuVBs
耦合效率的计算有一个积分过程,还是比较复杂的.
