System Transmittance ]@*tfz\YaH
Suppose you need to calculate the system transmittance of an optical system. oz%h)#;
You would probably use the grid raytrace option, and the emitted flux is equal to HS{P?~:=U
the sum of the flux in all the emitted rays. When you display an irradiance map, {V[Ha~b%*
the system transmittance is equal to the total flux, displayed at the bottom of the k?^%hO>[
irradiance map window, divided by the emitted flux. To get the system jZrY=f
transmittance, check the Normalize to emitted flux box and press the Apply S\B5&W
button. The map will be redisplayed, and the Normalized Flux value will be equal "3@KRb4f
to the system transmittance.
