System Transmittance ]xhH:kW4
Suppose you need to calculate the system transmittance of an optical system. 5d|+ c<
You would probably use the grid raytrace option, and the emitted flux is equal to 5hB2:$C
the sum of the flux in all the emitted rays. When you display an irradiance map, #|lVQ@=
the system transmittance is equal to the total flux, displayed at the bottom of the qt%/0
irradiance map window, divided by the emitted flux. To get the system ^Cg@'R9
transmittance, check the Normalize to emitted flux box and press the Apply & aF'IJC
button. The map will be redisplayed, and the Normalized Flux value will be equal 1'5!")r
to the system transmittance.
