System Transmittance UHBXq;?&q
Suppose you need to calculate the system transmittance of an optical system. eH&F gmU
You would probably use the grid raytrace option, and the emitted flux is equal to f|RmAP;X,
the sum of the flux in all the emitted rays. When you display an irradiance map, OvdT* g=8*
the system transmittance is equal to the total flux, displayed at the bottom of the Hl*vS
irradiance map window, divided by the emitted flux. To get the system Ebg8qDE
transmittance, check the Normalize to emitted flux box and press the Apply r8k (L{W
button. The map will be redisplayed, and the Normalized Flux value will be equal [^H2'&]
to the system transmittance.
