Abstract
The invention relates to a self-centering arrangement of microstructured elements, particularly of microoptical components on a substrate serving as carrier. To provide microoptical components with projections that fit into corresponding recesses is known in the art. The invention provides a way to improve the mutual alignment of components (K,, K,) in that a deformation occurs when projections (Z,, Z,) are inserted into the recesses (A). This deformation may concern the projections or the recesses themselves or a molding material introduced between the projections and the recesses. The deformation improves the self-centering properties; in addition, manufacturing tolerances are more easily compensated. If the element cannot be provided with a suitable projection, an intermediate carrier is used, which is, for example, a plastic element produced by a LIGA process.
