Textures are always used on the surface of lenses to soften the light-dark cutoff line of the driving beam. At the same time, textures also help to achieve uniform light distribution. Some 90 % of all lenses for projection headlights produced by Docter Optics have textured surfaces.
This type of texture can be molded into the entire surface of a lens or part of the surface. It is also possible to produce lenses with several different textures on the surface.
Modulated lens surfaces have a slight wavy structure that causes the focal length of the lens to oscillate.
Micro-structures 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.
