THE ALIGNMENT OF THE OPTICAL SYSTEM FOR 216 COUDE FOCUS ECHELLE SPECTROMETER

本文简单介绍了用于中国２．１６米天文望远镜折轴焦点的阶梯光栅分光仪的总体方案，分析了其光学系统的装调要点与步骤，并制订切实可行的装调方案。

This paper gives a brief introduction about the structure of the echelle spectrometer which was installed at coude focus of the chinese 2 16 meter astronomical telescope.According to the design requirment of this echelle spectrometer,the main points and steps of alignment of optical system are analysed.Authors work out a practical alignment scheme in which the fewest auxiliary tools are used.
