Projection Micro Lens Arrays
Automotive
Next generation automotive lighting system
Automotive projection applications are an upcoming, rapidly growing segment. These projection systems, that can be used for functional or decorative purposes, enable unique external design coupled with lightweight, powerful and shaped illumination.
Micro lens array based projection systems transform the vehicule and its surroudings into a canvas for more safety and decorative functionalities. With the development towards autonomous driving, light will not only be needed for better visibility, but will also play a pivotal role for the communication of a vehicle to its environment.
In order to achieve perfect projection, high quality optical components are required. These replicated lens arrays, produced by nano-imprint or molding processes, get their replicated shapes from a unique master or molding tool. Thanks to its patented DPI® technology, Wielandts UPMT provides micro lens array molds or masters with incomparable quality and geometry freedom, for both ground projection and headlight applications.
