摘　　要：在光纤熔接过程中，为了实现光纤高质量熔接，需要一个高清显微物镜来确保纤芯的准确对准。运用Zemax软件设计一款用于光纤纤芯对准的显微物镜，该物镜由6片透镜组成，放大率为8倍，数值孔径为0．25，工作距为13．4mm，共轭距为85mm，以CCD作为图像接收器件。显微物镜采用正向光路进行优化设计，正向光路设计的显微物镜更能贴近实际使用状态，能够更加清晰准确地检测到纤芯位置。该物镜3-作波长为486～656nm，具有工作距离长、共轭距短、精度高等特点。According to the requirement of high-quality fiber fusion in the process of optical fiber fusion,a microscope objective for detecting the fiber core is designed to determine the position of the optical fiber core,which is optimized through the optical system design software Zemax.The designed system consists of six lenses.The magnification is eight.The object space NAis 0.25.The working distance is 13.4 mm.The conjugate distance is 85 mm and image receiver is a CCD.The optical lens is optimized through the method of forward optical path with the spectral range of 486~656nm.Forward optical path design of the microscope objective is practical to detect the fiber core position more clearly and accurately.It has long working distance,short conjugate distance and high accuracy.
