System Transmittance zw0w. "V
Suppose you need to calculate the system transmittance of an optical system. yIMqQSt79z
You would probably use the grid raytrace option, and the emitted flux is equal to #/)t]&n
the sum of the flux in all the emitted rays. When you display an irradiance map, u;#]eUk9}
the system transmittance is equal to the total flux, displayed at the bottom of the ]MbPivM
irradiance map window, divided by the emitted flux. To get the system mgs(n5V5
transmittance, check the Normalize to emitted flux box and press the Apply JxAQ,oOO
button. The map will be redisplayed, and the Normalized Flux value will be equal K =g</@L6R
to the system transmittance.
