摘要：

本文介绍了Lick天文台3米Shane望远镜上Shane自适应光学红外照相摄谱仪（Sharcs）的设计和早期科学性能。ShARCS旨在与新的ShaneAO自适应光学系统配合使用，能够在J、H和K波段进行高效、衍射极限成像和低色散棱镜光谱学。ShARCS使用HAWAII-2 RG红外探测器，提供高量子效率（>80%）和Nyquist采样在所有三个波段的衍射极限。ShARCS仪器还配备了线性偏振仪，灵敏度低至650 nm，以支持未来的可见光自适应光学能力。我们报告在调试期间采取的早期科学数据。

英文摘要：

We describe the design and first-light early science performance of the Shane Adaptive optics infraRed Camera-Spectrograph (ShARCS) on Lick Observatory's 3-m Shane telescope. Designed to work with the new ShaneAO adaptive optics system, ShARCS is capable of high-efficiency, diffraction-limited imaging and low-dispersion grism spectroscopy in J, H, and K-bands. ShARCS uses a HAWAII-2RG infrared detector, giving high quantum efficiency (>80%) and Nyquist sampling the diffraction limit in all three wavelength bands. The ShARCS instrument is also equipped for linear polarimetry and is sensitive down to 650 nm to support future visible-light adaptive optics capability. We report on the early science data taken during commissioning.
