System Transmittance '-2|GX_o
Suppose you need to calculate the system transmittance of an optical system. C'&t@@:
You would probably use the grid raytrace option, and the emitted flux is equal to $=ua$R4Z+
the sum of the flux in all the emitted rays. When you display an irradiance map, s $?u'}G3
the system transmittance is equal to the total flux, displayed at the bottom of the aUyJi
irradiance map window, divided by the emitted flux. To get the system Fu*Qci1Z
transmittance, check the Normalize to emitted flux box and press the Apply ~E3"s
button. The map will be redisplayed, and the Normalized Flux value will be equal VD0U]~CWR
to the system transmittance.
