Optical Thickness Measurement of Multilayer Films

Posted September 10, 2018 by Kristin

Abstract — Manufacturers of multi-layer films can realize significant cost savings, product quality improvements, and reduce the risk of product failures by accurately measuring individual layer thicknesses of multi-layer materials instead of relying on gauging that can only provide total thickness.

Online multilayer film system

Posted February 07, 2017 by Kristin

A customer presented Lumetrics with a 5 layer product constructed of a liner, adhesive, middle layer, adhesive and a liner.  The product is made in two operations.  The first operation coats the liner with adhesive then adds the middle layer.  The second operation adds adhesive to the middle layer and then adds the final  liner.

The ability to control the adhesive layer was a critical parameter.  The customer needed to know the adhesive thickness when applied in a wet state and again when cured in a dry state.
