System Transmittance WU\Bs2
Suppose you need to calculate the system transmittance of an optical system. pN=>q<]L
You would probably use the grid raytrace option, and the emitted flux is equal to j4%\'xj:
the sum of the flux in all the emitted rays. When you display an irradiance map, d~qZ;uw
the system transmittance is equal to the total flux, displayed at the bottom of the .k!<Oqa
irradiance map window, divided by the emitted flux. To get the system |BEoF[1
transmittance, check the Normalize to emitted flux box and press the Apply s{uSU1lQn
button. The map will be redisplayed, and the Normalized Flux value will be equal :d1Kq _\K
to the system transmittance.
