System Transmittance g(){wCI
Suppose you need to calculate the system transmittance of an optical system. `&]<_Jc1
You would probably use the grid raytrace option, and the emitted flux is equal to 'i#m%D`dt
the sum of the flux in all the emitted rays. When you display an irradiance map, IMjz#|c
the system transmittance is equal to the total flux, displayed at the bottom of the Vf<VKP[9K
irradiance map window, divided by the emitted flux. To get the system %GG:F^X#
transmittance, check the Normalize to emitted flux box and press the Apply .4DX/~F
button. The map will be redisplayed, and the Normalized Flux value will be equal 0]%0wbY1
to the system transmittance.
