简单介绍了经纬仪检定装置,设计一款可检定红外-可见双波段经纬仪的检定装置,并对该装置中卡塞格林平行光管进行了设计,运用Zemax光学设计软件对其系统进行了优化与分析,确定其非球面系数,通过点列图、MTF函数及能量分布对其像质进行简要分析从而确定了该设计的可行性与合理性,最后通过实验数据设计了与之匹配的光管的机械结构。

With the rapid development of modern technology, theodolite test device received a lot of attention.This paper introduces the structure of theodolite test device briefly. We designed a theodolite test device which could test dual-band theodolite, and designed the Cassegrain collimator. We utilized Zemax optical design tool to design and analyse the optical system. We determined the aspheric coefficient. In the analysis of the spot diagram, MTF function and energy distribution over the image quality, we determined the feasibility and rationality of the design. Finally based on the analysis,we designed mechanical structure.
