论文摘要
Scales是一个高对比度，红外冠状成像仪和整体场谱仪（IFS）（IFS），该光谱仪（IFS）将部署在W.M. M.凯克天文台自适应光学系统。反射光学设计允许在大波长范围（1.0-5.0微米）上进行衍射限制成像。基于Microlens阵列的IFS与Lenslet Reformatter（“ Slenslit”）结合使用，可以在低（r = 35-250）和中度（R = 2000-6500）频谱分辨率下进行光谱。较大的波长范围，衍射有限的性能，高对比度的冠状动脉和低温操作提出了独特的光学设计挑战。我们提供完整的光学设计，包括性能建模，分析和制造。
SCALES is a high-contrast, infrared coronagraphic imager and integral field spectrograph (IFS) to be deployed behind the W.M. Keck Observatory adaptive optics system. A reflective optical design allows diffraction-limited imaging over a large wavelength range (1.0 - 5.0 microns). A microlens array-based IFS coupled with a lenslet reformatter ("slenslit") allow spectroscopy at both low (R = 35 - 250) and moderate (R = 2000 - 6500) spectral resolutions. The large wavelength range, diffraction-limited performance, high contrast coronagraphy and cryogenic operation present a unique optical design challenge. We present the full SCALES optical design, including performance modeling and analysis and manufacturing.
