System Transmittance 6-D%)Z(
Suppose you need to calculate the system transmittance of an optical system. 22l|!B%o
You would probably use the grid raytrace option, and the emitted flux is equal to E=$7ieW
the sum of the flux in all the emitted rays. When you display an irradiance map, =ltbS f7
the system transmittance is equal to the total flux, displayed at the bottom of the =c
:lS&B
irradiance map window, divided by the emitted flux. To get the system l_UXrnm/N
transmittance, check the Normalize to emitted flux box and press the Apply J,CJPUf&
button. The map will be redisplayed, and the Normalized Flux value will be equal FRb&@(;
to the system transmittance.
