System Transmittance TDFkxB>
Suppose you need to calculate the system transmittance of an optical system. Po__-xN>Q
You would probably use the grid raytrace option, and the emitted flux is equal to :Q $K<)[
the sum of the flux in all the emitted rays. When you display an irradiance map, K]s[5
the system transmittance is equal to the total flux, displayed at the bottom of the LcB]Xdsa(
irradiance map window, divided by the emitted flux. To get the system -0$55pa/@:
transmittance, check the Normalize to emitted flux box and press the Apply } z _
button. The map will be redisplayed, and the Normalized Flux value will be equal b[t> te
to the system transmittance.
