算光效率 ,可以尝试使用归一化啊。 K>w}(td System Transmittance #xm<|s Suppose you need to calculate the system transmittance of an optical system. ORp6 You would probably use the grid raytrace option, and the emitted flux is equal to ^qy$M> the sum of the flux in all the emitted rays. When you display an irradiance map, mQ('X~l the system transmittance is equal to the total flux, displayed at the bottom of the )p(5$AR7 irradiance map window, divided by the emitted flux. To get the system "7l p|0I transmittance, check the Normalize to emitted flux box and press the Apply {ZY^tTsY button. The map will be redisplayed, and the Normalized Flux value will be equal wvp\'* $ to the system transmittance.
