算光效率 ，可以尝试使用归一化啊。 {W,&jC
System Transmittance 2M@,g8O+B=
Suppose you need to calculate the system transmittance of an optical system. BS!VAHO"V
You would probably use the grid raytrace option, and the emitted flux is equal to ;<hLy(@
the sum of the flux in all the emitted rays. When you display an irradiance map, sN"<baZ
the system transmittance is equal to the total flux, displayed at the bottom of the OlI|.~
irradiance map window, divided by the emitted flux. To get the system Qq+$ea?>
transmittance, check the Normalize to emitted flux box and press the Apply u7 L&cx
button. The map will be redisplayed, and the Normalized Flux value will be equal opqY@>Vh&
to the system transmittance.
