METHOD FOR THE PRODUCTION OF A PROBE TIP, PARTICULARLY FOR NEAR-FIELD OPTICAL MICROSCOPY, HAVING A DESIRED APERTURE

摘要

The invention relates to a method for the production of a probe tip (10) for optical examinations, particularly for near-field optical microscopy, having a desired aperture, wherein at least one optically transparent intermediate layer (14) is provided in a light conducting fiber (12) with a peripheral surface (12c) tapering towards the free end thereof between said peripheral surface (12c) and an optically non-transparent layer (18/20) that is applied on said peripheral surface (12c). The thickness of the intermediate layer is chosen depending on the desired aperture. This makes it possible to produce probe tips (10) using a simple and scalable method.
