We perform a large-scale Monte Carlo simulation of the three-dimensional Ising model on simple cubic lattices of size L^(3) with L5128 and 256. We determine the corresponding structure factor (Fourier transform of the two-point function) and compare it with several approximations and with experimental results. We also compute the turbidity as a function of the momentum of the incoming radiation, focusing in particular on the deviations from the Ornstein-Zernike expression of Puglielli and Ford.
