本文旨在介绍列日大学研制的新型近红外光纤馈电光谱仪NƎSIE的性能。该仪器是在列日空间中心开发、对准和测试的，2017年10月实现了第一次亮相。本文将通过对准过程和光学性能验证，最终介绍第一次光观测。NƎSIE的最终位置将是位于墨西哥拉卢斯的TIGRE望远镜。这台仪器提供的观测数据将帮助列日大学的几个研究小组研究大质量恒星。特别是，通过将收集到的光谱与理论模型进行比较，将改进演化模型。因此，这种合作将有助于更好地了解大质量恒星和这些非凡天体内发生的机制。
Our contribution intends to present the obtained performances of the NƎSIE instrument, a new near-infrared fiber-fed spectrograph developed at the University of Liège. This instrument was developed, aligned and tested at the Centre Spatial de Liège and first light was achieved in October 2017. This paper will go through the alignment process and optical performance verification to eventually introduce the first light observations. The final location of NƎSIE will be the TIGRE telescope located in La Luz, Mexico. The observational data provided by this instrument will help several research groups from the University of Liège to study massive stars. In particularly, evolution models will be improved through the comparison of the collected spectra with theoretical models. This collaboration will therefore contribute to a better understanding of massive stars and the mechanisms that take place within these extraordinary objects.
