Polarization is not a new phenomenon. However, in some applications polarization can be a contributing factor to colorimetric mismatch between samples When investigating polarization effects, most work has centered on the application of circular polarization on absorption spectroscopy in organic molecules. However, little if any colorimetric research on plastic materials has been done. Given the fact that linear polarization is a naturally occurring phenomenon, the dichroic effect is further highlighted in some end-user applications. The current research defines a technique for characterizing the linear-polarization-induced dichroic effect in a transmitting plastics application. Included in the work is the description of a polar-spectrophotometer capable of defined illumination and collection polarization states. Sample measurements and data analysis techniques are also discussed.
