Measuring the Opacity of Plastic Tubing with Vis-NIR Transmission Spectroscopy

contributed by Ocean Optics | 06/24/2014

Plastic tubing is available in a variety of opacities ranging from clear to translucent. The transparency of plastic tubing varies for reasons such as providing contrast for visual monitoring of fluid flow, decreasing exposure to ambient light, and making the tubing more distinct for machine vision technology. Visible-NIR transmission spectroscopy is used to assess the amount of frosting applied to plastic tubing to determine if the tubing meets the required opacity level.
