Hi Eric,

Let us know if Benton's reply at:

http://hypernews.slac.stanford.edu/HyperNews/geant4/get/opticalphotons/226/3.html

is not helping you enough.

You should define your optical photon spectra over the same energy range for all processes (if only to avoid G4 warning messages). You then define WLS absorption length to be short in the energy range where you expect an original scintillation photon to be absorbed and re-emitted but you define the WLS absorption (and bulk absorption) length to be much larger than your typical trajectory in the energy range where you expect your medium to be transparent.
