System Transmittance at(gem
Suppose you need to calculate the system transmittance of an optical system. P_(<?0l
You would probably use the grid raytrace option, and the emitted flux is equal to 5uU{!JuSa
the sum of the flux in all the emitted rays. When you display an irradiance map, rd^j<
the system transmittance is equal to the total flux, displayed at the bottom of the caZEZk#r;
irradiance map window, divided by the emitted flux. To get the system ceAefKdb
transmittance, check the Normalize to emitted flux box and press the Apply W=4|ahk$
button. The map will be redisplayed, and the Normalized Flux value will be equal [Vj|fy4
to the system transmittance.
