System Transmittance !gRU;ZQU_
Suppose you need to calculate the system transmittance of an optical system. #UymD-yII
You would probably use the grid raytrace option, and the emitted flux is equal to \R@}X cqZ
the sum of the flux in all the emitted rays. When you display an irradiance map, ,B/TqPP
the system transmittance is equal to the total flux, displayed at the bottom of the ~I>|f
irradiance map window, divided by the emitted flux. To get the system GYIQ[#'d7
transmittance, check the Normalize to emitted flux box and press the Apply 6Zw$F3 <
button. The map will be redisplayed, and the Normalized Flux value will be equal rt vLLOIO
to the system transmittance.
