System Transmittance 5z Kqb
Suppose you need to calculate the system transmittance of an optical system. c]NN'9G!{
You would probably use the grid raytrace option, and the emitted flux is equal to O1'K>teF%
the sum of the flux in all the emitted rays. When you display an irradiance map, WqQU@sA
the system transmittance is equal to the total flux, displayed at the bottom of the X3yS5whd(
irradiance map window, divided by the emitted flux. To get the system Cfv]VQQE
transmittance, check the Normalize to emitted flux box and press the Apply 96}eR,
button. The map will be redisplayed, and the Normalized Flux value will be equal NO4Z"3Pd_
to the system transmittance.
