These specialty films are holographic microstructures originated using Holographic Interference. These are primarily diffraction gratings used to create colorful and eye-catching effects. The structures can be arranged in various shapes and sizes using our recombining techniques to create diffractive colors that are pure color or pastel colors depending on the frequency of the diffraction grating used. Standard holographic films are Rainbow, Sparkle dots, and Cracked Ice. We have recently created a line of pure white sparkle patterns. WFT has an extensive library of diffraction grating frequencies which includes the largest crossed diffraction grating (Seamless Rainbow) in the world (65-inch square). Most of our holographic library is utilized in combination with our world class Fresnel lens library to create hybrid layouts. The holographic patterns lend brightness and 'sparkle' to the eye-catching 3D depth and movement of our Fresnel lens patterns.
