System Transmittance >2#8B
Suppose you need to calculate the system transmittance of an optical system. AwQ?l(iZ"p
You would probably use the grid raytrace option, and the emitted flux is equal to v\(2&*
the sum of the flux in all the emitted rays. When you display an irradiance map, g{5A4|_7
the system transmittance is equal to the total flux, displayed at the bottom of the f/CuE%7BR
irradiance map window, divided by the emitted flux. To get the system C6rg<tCH
transmittance, check the Normalize to emitted flux box and press the Apply Z7 E
button. The map will be redisplayed, and the Normalized Flux value will be equal JN7k 2]{
to the system transmittance.
