System Transmittance Z\EA!Cs3
Suppose you need to calculate the system transmittance of an optical system. \20}/&
You would probably use the grid raytrace option, and the emitted flux is equal to ]W14'Z
the sum of the flux in all the emitted rays. When you display an irradiance map, 1(dKb
the system transmittance is equal to the total flux, displayed at the bottom of the !CcDA/0
irradiance map window, divided by the emitted flux. To get the system MO0NNVVi%U
transmittance, check the Normalize to emitted flux box and press the Apply WV.hQX9P
button. The map will be redisplayed, and the Normalized Flux value will be equal %" 7UYLX
to the system transmittance.
