System Transmittance %McE` 155
Suppose you need to calculate the system transmittance of an optical system. _)T5lEFl=
You would probably use the grid raytrace option, and the emitted flux is equal to kM8{C w
the sum of the flux in all the emitted rays. When you display an irradiance map, iBTYY{-wF
the system transmittance is equal to the total flux, displayed at the bottom of the V[o`\|<
irradiance map window, divided by the emitted flux. To get the system n+;6=1d7ZW
transmittance, check the Normalize to emitted flux box and press the Apply O m;&_!i
button. The map will be redisplayed, and the Normalized Flux value will be equal 7*5Z
to the system transmittance.
