标题： The Fibre Multi-Object Spectrograph (FMOS) for Subaru Telescope

摘要： 光纤多目标光谱仪（FMOS）是第一个具有宽视场的近红外仪器，能够同时从最多400个天体获取光谱。 它被开发为昴星团望远镜F/2主焦点的通用仪器。 通过一个在近红外（0.9-1.8um）波长范围内优化的新三元件校正器实现了30'直径的视场覆盖。 由于主焦点空间有限，我们不得不开发一种名为“Echidna”的新型光纤定位器以及两个抑制OH空气辉光的光谱仪。 FMOS由三个子系统组成：红外主焦点单元，光纤定位系统/连接单元，以及两个光谱仪。 在完成全部系统集成后，FMOS于2007年底安装在望远镜上。 通过各种测试和工程观测检查了性能的各个方面。 在本文中，我们介绍了FMOS的光学和机械部件，并展示了至今为止的现场工程观测结果。 显示英文摘要

摘要： Fibre Multi-Object Spectrograph (FMOS) is the first near-infrared instrument with a wide field of view capable of acquiring spectra simultaneously from up to 400 objects. It has been developed as a common-use instrument for the F/2 prime-focus of the Subaru Telescope. The field coverage of 30' diameter is achieved using a new 3-element corrector optimized in the near-infrared (0.9-1.8um) wavelength range. Due to limited space at the prime-focus, we have had to develop a novel fibre positioner called "Echidna" together with two OH-airglow suppressed spectrographs. FMOS consists of three subsystems: the prime focus unit for IR, the fibre positioning system/connector units, and the two spectrographs. After full systems integration, FMOS was installed on the telescope in late 2007. Many aspects of performance were checked through various test and engineering observations. In this paper, we present the optical and mechanical components of FMOS and show the results of our on-sky engineering observations to date.
