System Transmittance vDu0
Suppose you need to calculate the system transmittance of an optical system. (t]lP/
You would probably use the grid raytrace option, and the emitted flux is equal to v\vE^|-\/
the sum of the flux in all the emitted rays. When you display an irradiance map, o~i]W.SI(
the system transmittance is equal to the total flux, displayed at the bottom of the o7_MMeQ4
irradiance map window, divided by the emitted flux. To get the system ?RgU6/2
transmittance, check the Normalize to emitted flux box and press the Apply +zFV~]b
button. The map will be redisplayed, and the Normalized Flux value will be equal /E`l:&89)
to the system transmittance.
