Suppose you need to calculate the system transmittance of an optical system. \).Nag +
You would probably use the grid raytrace option, and the emitted flux is equal to l<:`~\#
the sum of the flux in all the emitted rays. When you display an irradiance map, }%eDEM
the system transmittance is equal to the total flux, displayed at the bottom of the @. "q
irradiance map window, divided by the emitted flux. To get the system ~6p5H}'H1
transmittance, check the Normalize to emitted flux box and press the Apply __8&Jv\
button. The map will be redisplayed, and the Normalized Flux value will be equal z4CJn[m9
to the system transmittance.
