System Transmittance b9EJLD
Suppose you need to calculate the system transmittance of an optical system. ,qiS;2(
You would probably use the grid raytrace option, and the emitted flux is equal to r d]HoFE
the sum of the flux in all the emitted rays. When you display an irradiance map, Y8.0R-:ZAN
the system transmittance is equal to the total flux, displayed at the bottom of the x0.&fCh%
irradiance map window, divided by the emitted flux. To get the system %'\D_W&
transmittance, check the Normalize to emitted flux box and press the Apply |:!#kA
button. The map will be redisplayed, and the Normalized Flux value will be equal DBCL+QHA
to the system transmittance.
