| 摘 要： | 该文利用ZEMAX设计软件设计了远摄比小、前正组项焦距长的全站仪物镜，讨论了结构选取、各组元光焦度分配、负组调焦距离与视距的数值关系等问题。设计的物镜焦距厂f'为250mm，总长为142mm，前正组顶焦距大于95mm，最小视距为2m。设计中应用ZEMAX Program Language建立操作符对前组项焦距进行控制。结果表明．设计的物镜远摄比小．像差得到很好校正。

| Abstract: | An objective used in a total station with small telephoto ratio and long back focal length (BFL) of its positive front component was designed with ZEMAX software.Some problems of choosing its configuration,getting each component's power and the numerical relationship of the negative component's moving distance and the object distance were investigated.The focal length of this objective is 250 mm,but total length only 142 mm.In this objective,the BFL of its positive front component is more than 95 mm and its nearest object distance is 2 m.The BFL is controlled with the operand written in ZEMAX program language.The results show that the designed objective has very small telephoto ratio and its aberrations are effectively calibrated. |
