摘要
本文介绍了云南天文台一米望远镜附属的一台低色散光谱仪实验装置,介绍了该装置的设计原理、系统结构参数及试观测情况,并讨论了存在的问题和解决问题的设想。我们已用该装置观测到19m左右的具有大红移的类星体光谱。该类低色散光谱仪,将为我国星系研究工作者提供实测条件。
The principles of design, parameters of the system structure and test observations of a low dispersion spectrograph attached to the 1-m RCC telescope of the Yunnan Observatory are described. The problems which remain to be solved and the envisagements for solving them are also discussed in the present article. Using this device the spectra of some quasars of about 19m with large redshifts have been observed. This kind of low dispersion spectrographs will provide Chinese astronomers, especially those who are engaged in research on galaxies, with more powerful observational facility.
