Scattering in Zemax

I have a question about the Henyey Greenstein model in Zemax.

I am now using the Henyey-Greenstein (HG) model in combination with the wavelength shift to simulate the Raman scattering. Because the mean free path is wavelength-dependent in the same tissue, my question is that, in the multiple scattering, if the input photon is altered in wavelength, will its mean free path be changed too in the next scattering event? From the HG source code, it seems like the mean free path is a constant to all wavelengths. Furthermore, I also found from your HG source code that you didn't really consider the light absorption while in scattering events, right?

Thanks in advance!
