3DCD has paved the way in innovation with its many optical disc protection technologies and most recently with its robustly secure and visually stunning cdi technology (Coherent Diffractive Imaging). Utilizing a fully digital high definition LBR (Laser Beam Recorder) system, cdi has the capability to produce micro fringes ranging from shallow to very deep and to quickly expose much larger areas than e-beam technology. cdi is capable of a much greater range of optical features and techniques than other systems and is much brighter and more flexible than traditional holography. The cdi system is compatible with a wide range of photo-resists and developers and allows for customizable fringe widths and duty cycle control to accommodate a vast range of products and applications.
The cdi system was developed from the ground-up to be a leader in secure diffractive imaging technology. Offering a broad range of anti-counterfeiting effects and features, cdi has proven itself through its use in major software applications released worldwide. From “frameless” stereogram imagery and full-color two-channel effects to its ability to produce large customizable diffractive and axicon lenses, cdi is a unique, innovative and secure technology.
