摘要
我国第一架水平子午环,其有效口径在世界上为最大,于1990年4月在陕西天文台临时观测室安装就绪。由于水平子午环结构上的特点,给各光学系统进行精确调整使之达到实用要求带来了不少困难。本文主要叙述了该子午环的光学结构及对主光路和准直光路的调整要求。我们采用逐步逼近的调整方法,实践证明该方法是行之有效的。
The first meridian circle of China has been installed at CSAO in April 1990. This horizontal reflecting transit circle with 240ram effective aperture is developed by CSAO,NAIF and CUO.The optical system has been adiusted accurately based on the primary installation.Because of the constructional characteristics of the horizontal meridiam circle, there are some diffeculties for the adjustment. However the practice has verified that the method of approximating step by step is very successful. Now the optical system has reached the required level. We expect to obtain the preliminary observational result in the near future.
