We demonstrated a mechanical iris-based fiber optic probe with adjustable spatial offsets for spatially offset Raman spectroscopy (SORS). In the fiber probe, the excitation fiber was fixed at the center of the iris, and the collection fibers were movable with blades of the iris. Moreover, we studied the gap effect between the probe and the sample and demonstrated this fiber optic probe can be used as a platform for surface-enhanced SORS applications. This fiber probe design could potentially provide a design-efficient and cost-effective solution for various Raman applications.
我们展示了一种基于机械虹膜的光纤探头，用于空间偏移拉曼光谱（SORS），其具有可调节的空间偏移。在该光纤探头中，激发光纤固定在虹膜中心，而收集光纤可随虹膜叶片移动。此外，我们研究了探头与样品之间的间隙效应，并证明了这种光纤探头可作为表面增强SORS应用的平台。这种光纤探头设计有可能为各种拉曼应用提供一种设计高效且经济高效的解决方案。
