A method and the associated apparatus for alignment and assembly of microlenses and microcolumns in which aligning structures such as rigid fibers are used to precisely align multiple microlens components. Alignment openings are formed in the microlens components and standard optical fibers are threaded through the openings in each microlens component as they are stacked. The fibers provide sufficient stiffness and stability to the structure to precisely align the apertures of the microlens components and thereby allow for increased assembly efficiency over traditional microlens and microcolumn bonding techniques.

La présente invention concerne un procédé et l'appareil associé permettant l'alignement et l'assemblage de microlentilles et de microcolonnes, dans lesquels on utilise des structures d'alignement telles que des fibres rigides pour aligner avec précision plusieurs composants de microlentille. Des ouvertures d'alignement sont formées dans les composants de microlentille et des fibres optiques ordinaires sont enfilées à travers les ouvertures dans chaque composant de microlentille au fur et à mesure que ces composants sont empilés. Ces fibres fournissent une rigidité et une stabilité suffisantes à la structure pour aligner précisément les ouvertures des composants de microlentille et permettre de la sorte une efficacité d'assemblage améliorée par rapport aux techniques de liaison de microlentilles et microcolonnes traditionnelles.
