System Transmittance PAF8W lg
Suppose you need to calculate the system transmittance of an optical system. N"7]R[*
You would probably use the grid raytrace option, and the emitted flux is equal to Dl\`
the sum of the flux in all the emitted rays. When you display an irradiance map, bn9;7`>.
the system transmittance is equal to the total flux, displayed at the bottom of the EG<s_d?
irradiance map window, divided by the emitted flux. To get the system *C |
transmittance, check the Normalize to emitted flux box and press the Apply 2umv|]n+l|
button. The map will be redisplayed, and the Normalized Flux value will be equal @C8DZ5)
to the system transmittance.
