System Transmittance !ii(2U
Suppose you need to calculate the system transmittance of an optical system. ujBm"p_|
You would probably use the grid raytrace option, and the emitted flux is equal to a=y%+E'a'
the sum of the flux in all the emitted rays. When you display an irradiance map, D$H&^,?N
the system transmittance is equal to the total flux, displayed at the bottom of the 5Rw2/J
L
irradiance map window, divided by the emitted flux. To get the system G,P
k3>I'
transmittance, check the Normalize to emitted flux box and press the Apply &FOq c
button. The map will be redisplayed, and the Normalized Flux value will be equal Lk$Mfm5"M
to the system transmittance.
