Textures are used on the surface of lenses whenever it is advantageous to soften the light-dark cutoff line of the driving beam. At the same time, textures also help to achieve uniform light distribution. The DOC3D® precision-molding technology developed by Docter Optics makes it possible to mold textures directly into the surface of the lenses during the molding process. Some 90% of all lenses for projection headlights shipped by Docter Optics have textured surfaces.
Matted or frosted surfaces:
This type of texture can be molded into the entire surface of a lens or any part of the surface. It is also possible to produces lenses with several different textures or seamless transitions from one texture to another on the same surface.
Modulated lens surfaces feature a slightly wavy structure that causes the focal length of the lens to oscillate.
Microstructures consist of minute optical elements distributed over the surface of the lens that influence the distribution of the light and at the same time permit additional design possibilities.
