Производители полимерных изделий часто сталкиваются с необходимостью анализа дефектных изделий для определения причины возникновения брака и способов ее устранения. Для выполнения подобного анализа как правило применяются инфракрасная спектроскопия и спектроскопия комбинационного рассеяния (КР или Раман) для определения химического состава, спектрофотометрия в УФ и видимой областях для определения цвета и оптического пропускания, а также термический анализ для определения физических свойств. В настоящей статье описано исследование, использующее все эти методы для определения причин отказа прецизионного оптического изделия в процессе эксплуатации.

Manufacturers employing plastic parts routinely face the challenge of analyzing failed parts to determine the root cause and corrective actions. The tools used to perform this analysis often include infrared and Raman spectros-copy for chemical composition, UV-Visible spectroscopy for color and optical transmissivity, and thermal analysis for determination of physical properties. This paper describes a study utilizing all of these tools to determine why a plastic part used in a precision optical device failed when put into service.
