System Transmittance P`tOL#UeZL
Suppose you need to calculate the system transmittance of an optical system. " ityx?
You would probably use the grid raytrace option, and the emitted flux is equal to R
iZ)FW
the sum of the flux in all the emitted rays. When you display an irradiance map, -rDfDdT
the system transmittance is equal to the total flux, displayed at the bottom of the ]TvMT
irradiance map window, divided by the emitted flux. To get the system 6IqPZ{g9K'
transmittance, check the Normalize to emitted flux box and press the Apply pte\1q[N
button. The map will be redisplayed, and the Normalized Flux value will be equal y-pdAkDh
to the system transmittance.
