An optical element structured in accordance with the invention comprises a substrate with at least two zones with different optical functions. The coating systems in the two zones can in each case be subdivided into a zone-specific internal partial coating system and a complementary partial coating system that is common to all the zones, where the complementary partial coating system comprises at least one layer and in the zones in which the internal partial coating systems comprises at least one layer said coating system is arranged between the substrate and the complementary partial coating system.

Structured optical element and production thereof

A method of making a rotational optical arrangement and the arrangement made by the method, wherein the method includes providing a rotatable unit. The unit has a surface extending transverse to a center axis of the unit and at a predefined angle to an interface normal direction, and the unit having a pattern with at least two portions that each have a different optical characteristic. A mechanism is provided for rotating the unit around a mechanism-induced rotational axis. The center axis of the unit is separately aligned to the mechanism-induced rotational axis for radial offset correction. The interface normal direction is separately aligning to the mechanism-induced rotational axis for skew correction.
