Vorrichtung und Verfahren zur Herstellung einer optischen Apertur |
摘要 |
An apparatus for producing optical aperture is disclosed. A pressing body (6) has a plane covering a tip (1) and at least a part of stoppers (2). An opaque film (3) is 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. <IMAGE> |
