System Transmittance R8fB
8 )
Suppose you need to calculate the system transmittance of an optical system. 66Xo3o
You would probably use the grid raytrace option, and the emitted flux is equal to |ea}+N
the sum of the flux in all the emitted rays. When you display an irradiance map, :<`po4/
the system transmittance is equal to the total flux, displayed at the bottom of the zgA/B{DaC;
irradiance map window, divided by the emitted flux. To get the system TllIs&MCe
transmittance, check the Normalize to emitted flux box and press the Apply FFID<Lf/2
button. The map will be redisplayed, and the Normalized Flux value will be equal k>7 2W/L^
to the system transmittance.
