System Transmittance G^;>8r
Suppose you need to calculate the system transmittance of an optical system. Lja 7
You would probably use the grid raytrace option, and the emitted flux is equal to ^5; `-Ky
the sum of the flux in all the emitted rays. When you display an irradiance map, gE])!GMM3
the system transmittance is equal to the total flux, displayed at the bottom of the ,|h)bg7.
irradiance map window, divided by the emitted flux. To get the system oM1Qh?
transmittance, check the Normalize to emitted flux box and press the Apply NxA)@9Q
button. The map will be redisplayed, and the Normalized Flux value will be equal _S`o1^Ad
to the system transmittance.
