Optical Testing and Characterization^[1]

This article is a brief account of various factors pertinent to the characterization of materials and analysis of optical components, namely transmission, haze, yellowness, refractive index, surface irregularity, birefringence, internal contamination, surface gloss, and color. In addition, details on ad hoc tests used for determining the acceptability of a plastic part for its application are provided, along with typical examples.
