System Transmittance Cs1>bpY*R6
Suppose you need to calculate the system transmittance of an optical system. 5 DFZ^~
You would probably use the grid raytrace option, and the emitted flux is equal to {p/YCch,
the sum of the flux in all the emitted rays. When you display an irradiance map, g}Qx`65:
the system transmittance is equal to the total flux, displayed at the bottom of the \=nrt?
irradiance map window, divided by the emitted flux. To get the system T+CajSV
transmittance, check the Normalize to emitted flux box and press the Apply %l$W*.j|;
button. The map will be redisplayed, and the Normalized Flux value will be equal u\g,.C0
to the system transmittance.
