Measurement coupling light platform

The utility model discloses a measuring coupling optical platform which comprises a first multimode optical fiber, a first lens group and a first five-axis platform. The first lens group comprises a first collimating lens and a first focusing lens, the first collimating lens collimates a plurality of light beams emitted by a to-be-measured element, and the first focusing lens focuses the collimated light beams. The first five-axis platform is used for aligning the first multimode optical fiber and the first lens group with a to-be-measured element for coupling light, so that the light beams enter the fiber core of the first multimode optical fiber after being focused by the first focusing lens. 本实用新型公开一种测量耦光平台，其包含第一多模光纤、第一透镜组及第一五轴平台。第一透镜组包含第一准直透镜及第一聚焦透镜，第一准直透镜准直待测元件发出的多个光束，而第一聚焦透镜将准直后的该些光束聚焦。第一五轴平台用于将第一多模光纤及第一透镜组与待测元件对位以进行耦光，使该些光束被第一聚焦透镜聚焦后进入第一多模光纤的纤芯。
