System Transmittance P #2TM
Suppose you need to calculate the system transmittance of an optical system. l&^[cR
You would probably use the grid raytrace option, and the emitted flux is equal to s<r.+zqW
the sum of the flux in all the emitted rays. When you display an irradiance map, sm&rR=b
the system transmittance is equal to the total flux, displayed at the bottom of the qYu!:xa8
irradiance map window, divided by the emitted flux. To get the system )r|zi
Z {F
transmittance, check the Normalize to emitted flux box and press the Apply =< FZ{4
button. The map will be redisplayed, and the Normalized Flux value will be equal :jKXKY+T
to the system transmittance.
