System Transmittance DeVv4D:}@
Suppose you need to calculate the system transmittance of an optical system. ;fTKfa
You would probably use the grid raytrace option, and the emitted flux is equal to c^xIm'eob
the sum of the flux in all the emitted rays. When you display an irradiance map, LVM%"sd?
the system transmittance is equal to the total flux, displayed at the bottom of the Y(ykng
irradiance map window, divided by the emitted flux. To get the system >b}o~F^J
transmittance, check the Normalize to emitted flux box and press the Apply mthA4sz
button. The map will be redisplayed, and the Normalized Flux value will be equal g{)dP!}
to the system transmittance.
