System Transmittance :j#zn~7
Suppose you need to calculate the system transmittance of an optical system. {z9,CwJan?
You would probably use the grid raytrace option, and the emitted flux is equal to u/CR7Y
the sum of the flux in all the emitted rays. When you display an irradiance map, dP<i/@21Wm
the system transmittance is equal to the total flux, displayed at the bottom of the g7w#;E
irradiance map window, divided by the emitted flux. To get the system = eR#]d
transmittance, check the Normalize to emitted flux box and press the Apply tI
button. The map will be redisplayed, and the Normalized Flux value will be equal
T4J
WZ
to the system transmittance.
