The invention belongs to the technical field of optics, and particularly relates to a low-numerical-aperture Y-shaped optical fiber bundle matched with slit output of a monochromator, the overall structure of the optical fiber bundle is a Y-shaped one-to-two optical fiber bundle, and the numerical aperture NA of the optical fiber bundle is equal to 0.1; the optical fiber bundle end face of the optical fiber input end is a 14 mm * 1 mm rectangle, and the optical fiber bundle end faces of the optical fiber output end A and the optical fiber output end B are circles with the diameter of 1.5 mm. The optical fiber bundle can be matched with a slit of a monochromator for use and has a low output light divergence angle, namely, a low-numerical-aperture Y-shaped optical fiber bundle, the optical fiber bundle is installed in an exit slit of a polychromator, the energy of emergent light can be improved to meet application requirements, and meanwhile real-time energy monitoring of the emergent light can be provided. 本发明
