Abstract

Ferrule-top cantilevers are a new generation of all-optical miniaturized devices for utilization in liquids, harsh environments, and small volumes [G. Gruca et al., Meas. Sci. Technol. 21, 094033 (2010)]. They are obtained by carving the end of a ferruled fiber in the form of a mechanical beam. Light coupled from the opposite side of the fiber allows detection of cantilever deflections. In this paper, we demonstrate that ferrule-top cantilevers can be used to develop ultra compact AFMs for contact mode imaging in air and in liquids with sensitivity comparable to that of commercial AFMs. The probes do not require any alignment procedure and are easy to handle, favoring applications also outside research laboratories.

摘要

插芯顶端悬臂是新一代全光学微型设备，可用于液体、恶劣环境和小体积环境中[G. 格鲁卡等人，《测量科学与技术》21, 094033 (2010)]。它们是通过将插芯光纤的末端雕刻成机械梁的形式而获得的。从光纤另一侧耦合的光可用于检测悬臂的偏转。在本文中，我们证明了插芯顶端悬臂可用于开发超紧凑型原子力显微镜，用于在空气和液体中进行接触模式成像，其灵敏度与商用原子力显微镜相当。这些探针不需要任何对准程序，易于操作，有利于在研究实验室之外的领域应用。
