摘要
本文介绍了为云台CCD—Coude光谱仪系统研制的星象切分器。计算表明,运用切分器可提高光力2个星等以上。文中讲述了原理并给出有关参数的选择。本星象切分器入射端面为直径1mm的圆面,出射端面为0.15的一线阵,共由38根光纤组成。
A fiber image slicer, consisting of 38 fibers, is made for the CCD-Coude spectrograph of the 1-m telescope at the Yunnan Observatory. Its input end is a circular surface with a diameter of 1mm and the output end is a line array of 6mm×0.15mm. The calculated results show that the resolving power of the spectrograph may be increased by 2 magnitudes with the help of the fiber image slicer.
