System Transmittance hwk] ;6[
Suppose you need to calculate the system transmittance of an optical system. v2rzHzFU
You would probably use the grid raytrace option, and the emitted flux is equal to 7`~0j6FY
the sum of the flux in all the emitted rays. When you display an irradiance map, ^+%bh/2_W
the system transmittance is equal to the total flux, displayed at the bottom of the ]Ls T
irradiance map window, divided by the emitted flux. To get the system /)v+|%U
transmittance, check the Normalize to emitted flux box and press the Apply a(IE8:yU`
button. The map will be redisplayed, and the Normalized Flux value will be equal [ {"x{;
to the system transmittance.
