Abstract

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.
