System Transmittance 5a6VMqQ6
Suppose you need to calculate the system transmittance of an optical system. Ox|TMSb^
You would probably use the grid raytrace option, and the emitted flux is equal to Li]k7w?H
the sum of the flux in all the emitted rays. When you display an irradiance map, 0U%Xm[:
the system transmittance is equal to the total flux, displayed at the bottom of the Co[n--@C
irradiance map window, divided by the emitted flux. To get the system x~z_,':
transmittance, check the Normalize to emitted flux box and press the Apply fx]eDA|$e
button. The map will be redisplayed, and the Normalized Flux value will be equal ZL=N[XW4'
to the system transmittance.
