论文摘要
鳞片（用于外球星光谱的镜头的Santa Cruz阵列）是2-5微米的高对比度透镜整体场光谱仪（IFS），该光谱仪（IFS）由系外行星表征科学要求驱动，并将在W. M. Keck Persvatory上运行。它的完全低温光学火车使用定制的硅透镜阵列，可选的冠状动脉和分散棱镜在凯克（Keck）的2.2 ARCSEC视野上进行较低（$ <300 $）光谱分辨率的凯克（Keck）上的ARCSEC视野。 Lenslet阵列的一个小型专用部分为允许中等光谱分辨率（$ 5000-10 000 $）的图像切片机模块提供了图像切片机模块，以前尚未在衍射限制下使用coronagraphic仪器。与以前的IFS系外行星仪器不同，鳞片能够表征寒冷系外行星和棕色矮人的气氛（$ <600 $ k），在bandpasses中，这些身体在捕获相关的分子光谱特征的同时发出了大部分辐射。
SCALES (Santa Cruz Array of Lenslets for Exoplanet Spectroscopy) is a 2-5 micron high-contrast lenslet integral-field spectrograph (IFS) driven by exoplanet characterization science requirements and will operate at W. M. Keck Observatory. Its fully cryogenic optical train uses a custom silicon lenslet array, selectable coronagraphs, and dispersive prisms to carry out integral field spectroscopy over a 2.2 arcsec field of view at Keck with low ($<300$) spectral resolution. A small, dedicated section of the lenslet array feeds an image slicer module that allows for medium spectral resolution ($5000-10 000$), which has not been available at the diffraction limit with a coronagraphic instrument before. Unlike previous IFS exoplanet instruments, SCALES is capable of characterizing cold exoplanet and brown dwarf atmospheres ($<600$ K) at bandpasses where these bodies emit most of their radiation while capturing relevant molecular spectral features.
