| 中文摘要: |
| 针对大天区面积多目标天文望远镜的要求,提出了一种低分辨率光谱仪的设计方案。其特点是光栅作为系统的孔径光栏,将入列交错排列的光纤的输出端在子午面排成圆弧形,消除准直系统的彗差,象散和畸变,整个光学系统无渐晕。 |
| 英文摘要: |
| A low resolution spectrometer is designed for use at the Cassegrain focus of the LAMOST 4-meter telescope. In this spectrometer,a grating is used as aperture stop of system. 310 fibres are arranged two line. At the outputs of end the fibres are arranged in a curved slit in meridian plane. In collimator there is not coma,astigmation and distortion. |
