Optical sensor Gauging System

OPTYSCAN represents the latest technology on the market in film thickness gauging. Thanks to its compact design and the same film side sender / receiver reading allow the installationon the chill roll frame. The extrusion lines will benefit from these characteristics resulting compact and the gauging being very close to the die head will guarantee a fast feedback and control particular appreciated during the start-up process.

OPTYSCAN uses NIR (Near Infra-Red) technology. Its optical sensor is based on low coherence interferometry. The material is illuminated with a broadband near infrared light source; The optical head collects the reflection from upper and lower boundaries of the film and makes it possible to obtain the difference between the two measurements.
