算光效率 ，可以尝试使用归一化啊。 "J"=<_?
System Transmittance (I~
Suppose you need to calculate the system transmittance of an optical system. w1tM !4r
You would probably use the grid raytrace option, and the emitted flux is equal to _Ay^v#a
the sum of the flux in all the emitted rays. When you display an irradiance map, Y! L-5|G
the system transmittance is equal to the total flux, displayed at the bottom of the 86=W}eV1r
irradiance map window, divided by the emitted flux. To get the system G!Brt&_'
transmittance, check the Normalize to emitted flux box and press the Apply 6.)ug7aF
button. The map will be redisplayed, and the Normalized Flux value will be equal O(/~c Q
to the system transmittance.
