Dear Daren,

thanks for your reply.

I think I solved the issue which was, as you suggest, indeed related to the RINDEX array.

My RINDEX array for PbF2 is generated by a parametrization function found in the literature (see https://refractiveindex.info/?shelf=main&book=PbF2&page=Malitson for details). Unfortunately the validity range for this function does not include UV photon energies (E>4eV). When using it in the UV range, in some occasions it produced unphysical RINDEX values (n<1) and this generated the problem I was having.

I fixed this by using the parametrization function in the correct range and extended it to UV using RINDEX values from another source (Handbook of Optical Constants of Solids, E.D.Palik editor).

Thanks for the help.

Emanuele
