System Transmittance T U_' 1
Suppose you need to calculate the system transmittance of an optical system. 0O'M^[=d.8
You would probably use the grid raytrace option, and the emitted flux is equal to 7#"NKxb
the sum of the flux in all the emitted rays. When you display an irradiance map, hb*Y-$Zp
the system transmittance is equal to the total flux, displayed at the bottom of the ^jL)<y4`
irradiance map window, divided by the emitted flux. To get the system [\Wl~
a l
transmittance, check the Normalize to emitted flux box and press the Apply qfT9g>EF
button. The map will be redisplayed, and the Normalized Flux value will be equal - <x%
to the system transmittance.
