LOW-COST, SIMPLE MASS PRODUCTION OF LIGHT-GUIDING TIPS

摘要

The present invention concerns light-guiding tips and a method of making the same. A method of manufacturing a light-guiding element with at least one tip having an aperture at its apex for light to pass through said aperture comprising the steps of: forming a tip-like indent in a substrate; depositing a light-guiding photoresist layer which fills the tip-like indent and covers at least a part of the substrate; and structuring the photoresist layer to form the light-guiding element out of the photoresist.
