System Transmittance YEEgDw]BQ
Suppose you need to calculate the system transmittance of an optical system. ~B NLzt3%O
You would probably use the grid raytrace option, and the emitted flux is equal to V
ifQ@
the sum of the flux in all the emitted rays. When you display an irradiance map, i&r56m<
the system transmittance is equal to the total flux, displayed at the bottom of the NbD"O8dL~E
irradiance map window, divided by the emitted flux. To get the system 78s:~|WB<{
transmittance, check the Normalize to emitted flux box and press the Apply >@2l/x8;
button. The map will be redisplayed, and the Normalized Flux value will be equal rb/m;8v>
to the system transmittance.
