System Transmittance BG\g`NK}Z
Suppose you need to calculate the system transmittance of an optical system. J5b>mTvb
You would probably use the grid raytrace option, and the emitted flux is equal to 3GqvL_
the sum of the flux in all the emitted rays. When you display an irradiance map, -HutEbkjx
the system transmittance is equal to the total flux, displayed at the bottom of the B U
|]4
irradiance map window, divided by the emitted flux. To get the system "ph&hd}S
transmittance, check the Normalize to emitted flux box and press the Apply f mXU)
button. The map will be redisplayed, and the Normalized Flux value will be equal )FVW/{NF@q
to the system transmittance.
