Use of Optical Microscopy and Video Measurement Systems to Determine Thicknesses in Multilayer Films, 1993 Polymers, Laminations & Coatings Conference Proceedings
Diane North
One of the difficulties in the coextrusion of films is determining the thicknesses of the individual layers. The use of an optical microscope with a video overlay system will be described. This off-line procedure is simple, quick and extremely accurate. It is also a useful device for inspection purposes.
