System Transmittance 5H8]N#Y&
Suppose you need to calculate the system transmittance of an optical system. %6c[\ubr
You would probably use the grid raytrace option, and the emitted flux is equal to 9,8}4Y=GVI
the sum of the flux in all the emitted rays. When you display an irradiance map, rBR,lS$4
the system transmittance is equal to the total flux, displayed at the bottom of the \0.
c_
irradiance map window, divided by the emitted flux. To get the system IjJO;
transmittance, check the Normalize to emitted flux box and press the Apply {oQ.y
button. The map will be redisplayed, and the Normalized Flux value will be equal G1K72M}CW
to the system transmittance.
