| Abstract: | The paper reports on a device for the elimination of the interfernce fringes and the correction to the flat fields on the Coude-CCD spectragraph system at the Yunnan Observatory,which includes the optical layout,the light sourse and the mechanical installation of this system.The reasons and methods of the optical interfernce effects caused by the CCD,when used to obtain a high dispersion spectrum,and the correction to the flat fields are also introduced. |
