general里Aperture选项中的Object Space NA 和半导体激光器的数值孔径NA是不是一个意思？

hopebox:if the laser beam has propagated beyond Rayleigh Range then the geometrical object NA would serve a reasonable approximation.  (2012-07-24 21:28)  2FzS_\":I

我表述的略有些问题，应该是半导体激光器电源的光纤，我查过资料，两个NA是一样的意思，

if the laser beam has propagated beyond Rayleigh Range then the geometrical object NA would serve a reasonable approximation.
