论文摘要

我们介绍了尺度的设计（切片机与系外星形光谱的一系列镜头组合），这是一种新的2-5 micron Coronagraphic coronagraphic积分田间光谱仪，正在为Keck天文台构建。秤可实现低分辨率（R〜50）光谱，以及中分辨率（R〜4,000）光谱，目的是发现和表征热红外最亮的冷外行星。此外，Scales具有12x12英寸的视野成像仪，将用于凯克（Keck）的一般自适应光学科学。我们介绍了Scales的规范，其科学案例，其整体设计以及对其预期性能的模拟。此外，我们还提出了采购，制造，制造和测试长时间持续时间组件的进展。

We present the design of SCALES (Slicer Combined with Array of Lenslets for Exoplanet Spectroscopy) a new 2-5 micron coronagraphic integral field spectrograph under construction for Keck Observatory. SCALES enables low-resolution (R~50) spectroscopy, as well as medium-resolution (R~4,000) spectroscopy with the goal of discovering and characterizing cold exoplanets that are brightest in the thermal infrared. Additionally, SCALES has a 12x12" field-of-view imager that will be used for general adaptive optics science at Keck. We present SCALES's specifications, its science case, its overall design, and simulations of its expected performance. Additionally, we present progress on procuring, fabricating and testing long lead-time components.
