摘　　要：目前市场上现有的连续变倍望远镜物镜,总长在100mm以内的都不超过二十几倍,为进一步提高测量精度,使体积不至于太大且方便随身携带,以原有研究作品为雏形,利用Zemax光学设计软件,通过改变结构、布局和材料等,设置操作数控制像差和总长,最后优化得出一款30×连续变倍望远镜物镜,且总长在86mm以内.对产品的各种像差进行比较和分析,结果表明,像差量均很小,成像质量较高,可满足人眼分辨率要求.该产品有很强的实际应用价值,可大幅度提高利用连续变倍望远镜工具进行测量的精度.The current available afocal zoom telescope objective is difficult to achieve 30× with the total length less than 100 mm.In order to further improve the measurement accuracy,the volume is not too large and it is convenient to carry around,taking the original research work as the embryonic form,using Zemax optical design software,through changing the structure,layout and material,setting operation to control aberration and total length,finally,a 30×afocal zoom telescope objective with total length within 86 mm is optimized.Various aberrations of the products are compared and analyzed.The results show that the aberrations are small and the imaging quality is high,which can meet the requirements of human eye resolution.The product has a strong practical application value,and can greatly improve the accuracy of measurement by means of afocal zoom telescope tools.
