Abstract
An apparatus for producing optical aperture is disclosed. A pressing body has a plane covering a tip and at least a part of stoppers. An opaque film formed on the tip. The pressing body is displaced toward the tip for forming an aperture on a point of the tip. According to the apparatus, the amount of displacement of the plate can be controlled excellently by the stopper and can be made very small. Thus, the aperture having a uniform and small size can be produced on the point of the tip easily.
Claims35
An apparatus for forming an optical aperture, the apparatus comprising:
- an object having a tip with a pointed end, a plurality of stoppers disposed adjacent the tip, and an opaque film disposed on the tip and the stoppers;
- and a pressing body for pressing the pointed end of the tip, at least a part of each of the stoppers, and at least a part of the opaque film to form an optical aperture at the pointed end of the tip.
An apparatus for forming an optical aperture, the apparatus comprising:
- an object having a tip with a pointed end, a plurality of stoppers disposed adjacent the tip, and an opaque film disposed on the tip and the stoppers;
- at least one pressing body for pressing the pointed end of the tip, at least a part of each of the stoppers, and a least a part of the opaque film to form an optical aperture at the pointed end of the tip;
- and at least one loader for applying a loading force on the pressing body to press the pointed end of the tip, the part of each of the stoppers, and the part of the opaque film.
An apparatus for forming an optical aperture, the apparatus comprising:
- an object comprised of a substrate, a transparent layer disposed on the substrate, a tip disposed on the transparent layer and having a pointed end, a plurality of stoppers disposed on the transparent layer, and an opaque film disposed on the tip and the stoppers;
- and a pressing body for pressing the pointed end of the tip, at least a part of each of the stoppers, and at least a part of the opaque film to form an optical aperture at the pointed end of the tip.
An apparatus for forming an optical aperture, the apparatus comprising:
- a substrate;
- a probe tip supported by the substrate;
- a pressing device for pressing against an end of the probe tip to form an optical aperture at the end of the probe tip;
- and at least one stopping member supported by the substrate and engageable against the pressing device for controlling a pressing force applied by the pressing device on the end of the probe tip.
