提出了一种利用廉价的通信光纤制作扫描近场光学显微镜（SNOMs）光学探针的简单方法。在HF溶液的油酸界面处，在一个单一步骤中蚀刻尖端。然后用丙烯酸涂料涂覆所得的探针以屏蔽光，并且在顶点处自发地形成小的光学孔径。该方法很简单，需要几个小时的准备使用探针的数量。涂料的原始使用大大简化了通常通过昂贵且耗时的金属涂覆技术进行的纤维筛选过程。我们表明，提示是完全可操作的，我们表现出良好的光学分辨率（100 nm）。据我们所知，我们的方法使最便宜的SNOM探头在这个分辨率范围内。
We derived a simple method to fabricate scanning near field optical microscopes (SNOMs) optical probes from commercial cheap communication optical fibers. The tips are etched in one single step at the oil–acid interface of a HF solution. The resulting probes are then coated with acrylic paint in order to screen the light and a small optical aperture is spontaneously formed at the apex. The method is straightforward and requires a few hours for a number of ready to use probes. The original use of paint simplifies strongly the procedure of screening of the fiber that usually has been performed by costly and time consuming metal coating technique. We show that the tips are fully operational and we demonstrate a good optical resolving power (100 nm). As far as we know, our method makes the cheapest SNOM probes within this resolution range.
