A model based upon Mie theory was developed to calculate the amount of spectral infrared scattering caused by the presence of a porous second phase. Various in‐line transmission curves were calculated and used to characterize the scattering effects of pore size and concentration. The in‐line transmission from 2.5 to 10 fjim of ZnS samples hot‐pressed at 137.8,172.3, and 206.7 MPa was measured using Fourier transform infrared spectrophotometry and compared with calculated transmission curves. Good agreement with measured results was obtained only when a size distribution effect was included. From the analysis, a bimodal distribution of pores was found to give the best agreement which duplicates the measured transmission.
