System Transmittance RHBQgD$
Suppose you need to calculate the system transmittance of an optical system. Nc(CGl:
You would probably use the grid raytrace option, and the emitted flux is equal to i,^3aZwJ'
the sum of the flux in all the emitted rays. When you display an irradiance map, sM MtU@<x
the system transmittance is equal to the total flux, displayed at the bottom of the 9vyf9QE ;
irradiance map window, divided by the emitted flux. To get the system O6/ vFEB
transmittance, check the Normalize to emitted flux box and press the Apply %m dtVQ@
button. The map will be redisplayed, and the Normalized Flux value will be equal VQqBo~
to the system transmittance.
