摘要：

MOSAIC* is the multi-object spectrograph (MOS) for the ESO 39m European Extremely Large Telescope (ELT) approved to enter phase B at the of beginning 2023. MOSAIC combines visible and near-infrared channels, from resolved stars up to the most distant galaxies, with multi-object and multi-integral field spectroscopy capabilities. The NIR-spectrograph (130K-90K) is one sub-system of the NIR-channel, led by the Universidad Complutense de Madrid (UCM, Spain). The NIR Spectrograph (NIRSPEC) comprises 2 identical spectrographs, each one equipped with Teledyne H4RG science detectors (4kx4k, 15 mu m pixels). Each spectrograph operates at 130K (with detectors at 90K) and covers the 2 observing bands J (1 - 1.38 mu m) and H (1.43 - 1.85 mu m in low-resolution mode and 1.52 - 1.65 mu m in high-resolution mode). This paper presents the optical design of the NIRSPEC.
