System Transmittance rKyulgP
Suppose you need to calculate the system transmittance of an optical system. L
G5_\sY!
You would probably use the grid raytrace option, and the emitted flux is equal to <'SS IMr
the sum of the flux in all the emitted rays. When you display an irradiance map, jC{KI!kPt
the system transmittance is equal to the total flux, displayed at the bottom of the 7C,giCYU
irradiance map window, divided by the emitted flux. To get the system NVsaV;u
transmittance, check the Normalize to emitted flux box and press the Apply u'>94Gm}
button. The map will be redisplayed, and the Normalized Flux value will be equal 5r~jo7
to the system transmittance.
