| Zusammenfassung: | The invention relates to a form comprising a certain surface morphology of complex lenses useful for making a light diffuser and a method for making such a form.
Disclosed is a form comprising a surface having a morphology of complex lenses wherein the surface asperities have an amplitude of between 1 and 40 micrometers, a spatial frequency of between 1 and 100 complex lenses per square millimeter, and between 1 and 40 minor lenses per major lens. Also disclosed is a method for making such a form. |
