System Transmittance $MR1
*_\V
Suppose you need to calculate the system transmittance of an optical system. "S;4hO
You would probably use the grid raytrace option, and the emitted flux is equal to jj{:=lZB
the sum of the flux in all the emitted rays. When you display an irradiance map, RdX+:!lD
the system transmittance is equal to the total flux, displayed at the bottom of the b7sfr!t_d
irradiance map window, divided by the emitted flux. To get the system WsHDIp
transmittance, check the Normalize to emitted flux box and press the Apply d:'{h"M6
button. The map will be redisplayed, and the Normalized Flux value will be equal Ichg,d-M-K
to the system transmittance.
