【摘要】以普通的单模石英光纤为材料,改进熔融拉锥装置,利用有旋转曲面的凹面镜,实现了制作扫描隧道显微镜光纤探针的加工过程。实验表明,改进后的拉锥装置满足了制作纳米量级针尖曲率半径光纤探针的基本要求。更多还原

【Abstract】 The nanometer order optical fiber probes are fabricated from ordinary quartz fiber by means of combination of melting- pulling.Using a concave mirror with curve surface,realized the fabrication of the STM optical fiber.The experiment indicate that the equipment of pulling taper can fabricate the optical fiber probes which the radius of the needlepoint satisfied nanometer dimension.更多还原
