These specialty films are created from Linear and Circular Fresnel lenses. A Fresnel lens is a microstructure made of facets that bend or reflect light like a thick lens (see diagram). They can be made to either focus or spread light. These lenses are originated in our Diamond Turning Machine (DTM) Lab using a diamond tool to cut facets into a metal mold. WFT's DTM Lab has developed the largest library of Fresnel lens masters available in the industry today and continues to build on this capability. The benefit of a Fresnel lens used in a package is that it images the area in which the package is displayed so if you were standing in the isle of a store and someone walks between you and the package, the package will appear to have movement even when you are standing still which catches your eye and draws you to the package. We have created a variety of stock lens patterns that are innovative in their active motion and 3D depth. WFT has a patent on one of the most creative dimensional effects recently seen (patent # 7,298,533), that outlines the use of multiple focal length lenses and both positive and negative Fresnel lens arrays to simulate unbelievable depth and 'movement'. Custom layouts can be made to enhance your printed design. Lens films are currently used for holiday season tissue cartons, cosmetic packaging and beverage cartons, as well as video games and blockbuster DVD releases. WFT specializes in combining Fresnel lens structures with holographic patterns to form custom hybrid designs that offer a distinctive package appearance for our customers.
