System Transmittance 9+^)?JUYll
Suppose you need to calculate the system transmittance of an optical system. xBVOIc[4(
You would probably use the grid raytrace option, and the emitted flux is equal to & Y=0 0
the sum of the flux in all the emitted rays. When you display an irradiance map, ERV]N:(
the system transmittance is equal to the total flux, displayed at the bottom of the d@$| zr6
irradiance map window, divided by the emitted flux. To get the system > 0MP[
transmittance, check the Normalize to emitted flux box and press the Apply G/<zd)
button. The map will be redisplayed, and the Normalized Flux value will be equal eKvr1m- -
to the system transmittance.
