MEASUREMENT OF MULTI-LAYER STRUCTURES USING NON-CONTACT REFLECTIVE LIGHT TECHNOLOGY

摘要

There are over ten thousand extrusion and coating lines that require some sort of gauging to determine the thickness of coatings, interlayer thickness or overall thickness. There are various methods currently available to provide this information but none provide the speed and accuracy desired by today's manufacturers of sophisticated material structures. Current technology, developed by Lumetrics, allows rapid on-line and off-line inspection of multilayer translucent plastics and coating applications. Results of on-line and offline testing and inspection systems will be presented.
