System Transmittance x\6];SXX
Suppose you need to calculate the system transmittance of an optical system. <o~t$TH
You would probably use the grid raytrace option, and the emitted flux is equal to 5`{=`
the sum of the flux in all the emitted rays. When you display an irradiance map, K[*h+YO
the system transmittance is equal to the total flux, displayed at the bottom of the ed=n``P~}
irradiance map window, divided by the emitted flux. To get the system 0u>yT?jP
transmittance, check the Normalize to emitted flux box and press the Apply fjcr<&{:
button. The map will be redisplayed, and the Normalized Flux value will be equal J0Jr
BXCh
to the system transmittance.
