System Transmittance } @jT-t]P
Suppose you need to calculate the system transmittance of an optical system. e[J0+
x#;r
You would probably use the grid raytrace option, and the emitted flux is equal to b{lkl?@a
the sum of the flux in all the emitted rays. When you display an irradiance map, *M()z.N
the system transmittance is equal to the total flux, displayed at the bottom of the X"
;ly0Mb
irradiance map window, divided by the emitted flux. To get the system R6dD17
transmittance, check the Normalize to emitted flux box and press the Apply 30$Q5]T
button. The map will be redisplayed, and the Normalized Flux value will be equal O$ ;:5zT
to the system transmittance.
