MICROSTRUCTURES AND METHODS OF MANUFACTURING THE SAME

A method of forming a plurality of optical microstructures is disclosed. The method includes laser machining a plurality of holes onto a surface and electrolytically polishing at least the holes to remove debris created during the laser machining. Each hole at least partially defines a respective on...

Zusammenfassung:	A method of forming a plurality of optical microstructures is disclosed. The method includes laser machining a plurality of holes onto a surface and electrolytically polishing at least the holes to remove debris created during the laser machining. Each hole at least partially defines a respective one of the optical microstructures. L'invention concerne un procédé de formation d'une pluralité de microstructures optiques. Le procédé consiste à usiner au laser une pluralité de trous sur une surface et à polir électrolytiquement au moins les trous afin d'éliminer les débris créés au cours de l'usinage au laser. Chaque trou définit au moins partiellement une microstructure respective des microstructures optiques.
