System Transmittance H9?~#GPb
Suppose you need to calculate the system transmittance of an optical system. l@
K<p
You would probably use the grid raytrace option, and the emitted flux is equal to TjdY Ck]'
the sum of the flux in all the emitted rays. When you display an irradiance map, Gz:a1-x
the system transmittance is equal to the total flux, displayed at the bottom of the j|9 2
g
irradiance map window, divided by the emitted flux. To get the system o\#e7 Hqbh
transmittance, check the Normalize to emitted flux box and press the Apply G Kr
L
button. The map will be redisplayed, and the Normalized Flux value will be equal Os;\\~e5
to the system transmittance.
