中文摘要 AI 辅助

Slicer Combined with an Array of Lenslets for Exoplanet Spectroscopy(SCALES,用于系外行星光谱学的切片器与微透镜阵列组合)仪器是一台1-5微米成像仪和2-5微米积分场光谱仪,目前正在凯克II望远镜上进行调试。SCALES针对系外行星高对比度成像和光谱表征进行了优化,对较古老、更寒冷的系外行星的灵敏度高于现有仪器。其12.3英寸×12.3英寸成像通道设计用于复刻NIRC2的性能,低分辨率(R~35-200,视场2.2英寸×2.2英寸)和中分辨率(R~2500-5000,视场0.36英寸×0.34英寸)光谱模式相比凯克现有仪器具备新能力。本文呈现了SCALES实验室测试与调试的初步光学性能结果。

英文摘要

The Slicer Combined with an Array of Lenslets for Exoplanet Spectroscopy (SCALES) instrument is a 1-5 micron imager and 2-5 micron integral field spectrograph, currently being commissioned on the Keck II Telescope. SCALES is optimized for exoplanet high-contrast imaging and spectroscopic characterization, and will be sensitive to older, colder exoplanets than existing instrumentation. The 12.3" x 12.3" imaging channel is designed to replicate the capabilities of NIRC2, and the low (R~35-200, 2.2" x 2.2" FOV) and medium (R~2500-5000, 0.36" x 0.34" FOV) spectral resolution modes offer new capabilities compared to existing Keck instrumentation. We present preliminary optical performance results from laboratory testing and commissioning of SCALES.
