Abstract
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.
