Light Scatter in Optical Materials: Advanced Haze Modeling

A simple scatterometer was constructed and used to make optical scatter measurements for four haze-standard samples. The scatter data were compared with independent measurements collected using a more sensitive and validated scatterometer and the results compared well. The scatter data were then imported into a modeling environment and modified using various built-in scatter editors. The scatter model showed a similar trend to the laboratory measurements, but produced significantly lower scatter values. Additional scatter measurements were made, and implemented with a surface scatter model and a volumetric scatter model, adjusted with correction factors to try to improve the match between the model and the laboratory measurements.
