Optical Testing of Polymers
ASM International eBooks · 1995
Abstract Optical testing of plastics includes characterization of materials and analysis of optical components. This article focuses on procedures for testing various characteristics of optical components, including transmission and haze, yellowness, refractive index, birefringence, as well as surface irregularity, contamination, gloss, and color. It provides a short note on ad hoc testing, which is beneficial for practical applications in which lenses, prisms, and light pipes are being used and tested, as other test instruments are often not available.
