System Transmittance b0m1O. &I_
Suppose you need to calculate the system transmittance of an optical system. 0N_Ma' )i
You would probably use the grid raytrace option, and the emitted flux is equal to tG^Oj:
the sum of the flux in all the emitted rays. When you display an irradiance map, a!Z,~ V8
the system transmittance is equal to the total flux, displayed at the bottom of the wV W+~DJ
irradiance map window, divided by the emitted flux. To get the system ; vQ7[Pv.j
transmittance, check the Normalize to emitted flux box and press the Apply ,Y &Q,
button. The map will be redisplayed, and the Normalized Flux value will be equal 1a/@eqF''
to the system transmittance.
