算光效率 ，可以尝试使用归一化啊。 - wh
System Transmittance *JZ lG%z
Suppose you need to calculate the system transmittance of an optical system. Vd'=Fe;eB
You would probably use the grid raytrace option, and the emitted flux is equal to }hcY5E-n
the sum of the flux in all the emitted rays. When you display an irradiance map, oqzWL~
the system transmittance is equal to the total flux, displayed at the bottom of the E;An':j
irradiance map window, divided by the emitted flux. To get the system pnXwE-c_
transmittance, check the Normalize to emitted flux box and press the Apply m>*~ tP
button. The map will be redisplayed, and the Normalized Flux value will be equal OP\ L
to the system transmittance.
