System Transmittance wc0jhHZO

Suppose you need to calculate the system transmittance of an optical system. $CxKuB(
You would probably use the grid raytrace option, and the emitted flux is equal to 5 z~1Dw
the sum of the flux in all the emitted rays. When you display an irradiance map, Bp*K]3_
the system transmittance is equal to the total flux, displayed at the bottom of the 8/DS:uM
irradiance map window, divided by the emitted flux. To get the system @*F"Q1 wI
transmittance, check the Normalize to emitted flux box and press the Apply Ot$-!Y;<
button. The map will be redisplayed, and the Normalized Flux value will be equal pe0F0Ruy
to the system transmittance.
