摘　　要：介绍远焦小型变焦距物镜的设计原理及方法。合理选取物镜的光学参数使变焦距物镜小型化 ;选取透镜的玻璃材料校正物镜的色差 ;采用适应法光学自动设计程序进行像差平衡 ,提高变焦距物镜的像质。所设计的变焦距物镜适用于多种医用内窥镜图像显示系统 ,其像质可与高分辨率的CCD图像传感器匹配。The design methodology of miniature linear zoom objective lens of far-focus is presented. The appropriate optical parameters would miniaturize the zoom objective lens. Proper selection of the glass material can correct the chromatism. Aberration balancing with automatic correction software using adaptive method can improve the image quality. The designed zoom objective lens can be applied to various medical endoscope imaging systems with good image quality to match the high resolution of CCD image sensors.
