摘要: 为了实现体视显微镜物镜的大变倍比连续变焦,同时尽量避免使用非球面以及衍射元件,采用双组联动型变倍补偿形式,设计了大变倍比连续变焦距体视显微镜物镜系统。该系统实现0.8~16倍的20倍连续变焦,系统工作距离达到91 mm,后工作距离达到200 mm,双组联动型结构不仅实现了大变倍比,同时保证系统结构尽量简单。设计结果表明:双组联动型变倍补偿形式对实现大变倍比以及简化结构是有利的。通过对系统成像质量以及凸轮拟合曲线进行分析,系统组元移动曲线光滑,成像质量达到要求。Abstract: In order to achieve high-magnification in continuous zoom stereo microscope objective system and avoid using aspherical optics and diffractive elements, new methods of zoom compensation were adopted in zoom lens designing with double linkage moving lens groups. By choosing 6 zoom positions for designing and calculation, the zoom of 0.8~16(20∶1) stereo microscope objective system was achieved. The working distance of the system reached 91 mm, and the back focal length reached 200 mm. After analyzing modulation transfer function (MTF) and aberration of the optical system, the results show that this zoom stereo microscope objective system realizes high magnification and high imaging quality.
