WINERED是一种新型近红外（NIR）高分辨率光谱仪（HRS），追求尽可能高的灵敏度，以实现在近红外和光波长范围内的高精度光谱分析。WINERED覆盖0.9-1.35 μm（z，Y和J波段），具有三种模式（宽模式和两种Hires模式），最大光谱分辨率为R= 28，000和R= 70，000。为了实现这一目标，WINERED设计了前所未有的高仪器吞吐量（最高可达50%，包括阵列的量子效率），是其他现有光学/NIR HRS的三倍或更多。这主要是通过光学设计中的非白光瞳和无光纤馈送配置、适度（优化）波长覆盖和高吞吐量光栅的组合来实现的。WINERED的另一个突出特点是“温暖”的仪器，尽管红外（IR）观测。这种非低温（无冷停止）红外仪器最终成为可能，其组合为定制的10− 8级热截止滤波器，1.7 μm截止夏威夷-2 RG阵列，以及将红外阵列的直接热辐射减少到f/2立体角的冷挡板。即使在290 K的环境下，在0.9-1.35 μm的宽带内，热背景也被抑制在0.1光子像素-1秒-1以下。自2017年以来，WINERED已安装在ESO拉西拉天文台的3.58米新技术望远镜上。即使使用中等大小的望远镜，在自然视宁度条件下，WINERED也被证实提供了一个极限星等（信噪比= 30，积分时间为8小时），分别为宽模式J= 16.4等和海尔模式J= 15.1等。这些灵敏度与现有的附在具有AO的8-10米级望远镜上的NIR-HRS的灵敏度相当。WINERED型摄谱仪不仅对目前正在进行的超大型望远镜来说是一个关键，以减少开发成本和时间，而且对小型望远镜来说也是一个关键，以延长其寿命。
WINERED is a novel near-infrared (NIR) high-resolution spectrograph (HRS) that pursues the highest possible sensitivity to realize high-precision spectroscopy in the NIR as in the optical wavelength range. WINERED covers 0.9–1.35 μm (z, Y, and J-bands) with three modes (Wide mode and two Hires modes) at the maximum spectral resolutions of R= 28,000 and R= 70,000. For fulfilling the objective, WINERED is designed with an unprecedentedly high instrument throughput (up to 50% at maximum including the quantum efficiency of the array) that is three times or more than other existing optical/NIR HRSs. This is mainly realized by a combination of non-white pupil and no fiber-fed configuration in optical design, the moderate (optimized) wavelength coverage, and the high-throughput gratings. Another prominent feature of WINERED is" warm" instrument despite for infrared (IR) observations. Such non-cryogenic (no cold stop) IR instrument finally became possible with the combination of custom-made thermal-cut filter of 10− 8 class, 1.7 μm cutoff HAWAII-2RG array, and a cold baffle reducing the direct thermal radiation to the IR array into the solid angle of f/2. The thermal background is suppressed below 0.1 photons pixel− 1 s− 1 even in the wide band of 0.9–1.35 μm under the environment of 290 K. WINERED had been installed to the 3.58 m New Technology Telescope at La Silla Observatory, ESO, since 2017. Even with the intermediate size telescope, WINERED was confirmed to provide a limiting magnitude (for SNR= 30 with 8 hr. integration time) of J= 16.4 mag for the Wide mode and J= 15.1 mag for the Hires mode, respectively, under the natural seeing conditions. These sensitivities are comparable to those for the existing NIR-HRSs attached to the 8–10 m class telescopes with AO. WINERED type spectrographs may become a critical not only for the currently on-going extremely large telescopes to reduce the developing cost and time but also for smaller telescopes to extend their lives with long programs.
