System Transmittance M5uN1*
Suppose you need to calculate the system transmittance of an optical system. g_U69
z
You would probably use the grid raytrace option, and the emitted flux is equal to $}fA ;BP
the sum of the flux in all the emitted rays. When you display an irradiance map, $(U|JR@
the system transmittance is equal to the total flux, displayed at the bottom of the 3I+pe;
irradiance map window, divided by the emitted flux. To get the system .>n|#XK
transmittance, check the Normalize to emitted flux box and press the Apply q 0wVV
button. The map will be redisplayed, and the Normalized Flux value will be equal 5FxU=M1gF
to the system transmittance.
