欧几里得任务的目标是通过研究距离-红移关系和宇宙结构的演化来绘制黑暗宇宙的几何形状。NISP（近红外分光光度计）是两个欧几里得仪器之一，工作在近红外光谱区域（0.9-2μm）。该仪器由：由SiC结构、光学组件、滤光轮机构、光栅轮机构、校准单元和热控制组成的冷（140K）光机械子系统和基于16 Teledyne HAWAII2RG 2.4μm马赛克的检测子系统组成。检测分系统安装于光机械分系统结构上——由数据处理/探测器控制单元和仪表控制单元组成的热电分系统（280K）。本报告将介绍该仪器的结构、预期性能和技术关键挑战。这篇论文是代表欧几里得联盟发表的。
The Euclid mission objective is to map the geometry of the dark Universe by investigating the distance-redshift relationship and the evolution of cosmic structures. The NISP (Near Infrared Spectro-Photometer) is one of the two Euclid instruments operating in the near-IR spectral region (0.9-2μm). The instrument is composed of: - a cold (140K) optomechanical subsystem constituted by a SiC structure, an optical assembly, a filter wheel mechanism, a grism wheel mechanism, a calibration unit and a thermal control - a detection subsystem based on a mosaic of 16 Teledyne HAWAII2RG 2.4μm. The detection subsystem is mounted on the optomechanical subsystem structure - a warm electronic subsystem (280K) composed of a data processing / detector control unit and of an instrument control unit. This presentation will describe the architecture of the instrument, the expected performance and the technological key challenges. This paper is presented on behalf of the Euclid Consortium.
