论文摘要
Liger是一种自适应光学器件（AO）馈送成像仪和整体场光谱仪（IFS），旨在利用W.M.的Keck All-Sky Precision Precision Precision Precision Precision升级（KAPA）升级。凯克天文台。我们介绍了成像仪光学组件的设计和分析，包括光谱仪重新成像光学元件（RIO），该光谱将光束路径从成像仪焦平面转移到IFS片段切片机模块和镜头阵列。每个成像仪组件和前两个RIO机制都组装在一起，并在同一光板上单独对齐。令人困惑的是，抑制背景辐射和散落的光线，并且瞳孔观看摄像头使成像仪检测器可以专注于望远镜学生的图像。光板安装在适配器框架上，以使整体系统对齐。在最终科学低温恒温器安装之前，将在低温测试室中表征成像仪和里约热内卢。
Liger is an adaptive optics (AO) fed imager and integral field spectrograph (IFS) designed to take advantage of the Keck All-sky Precision Adaptive-optics (KAPA) upgrade for the W.M. Keck Observatory. We present the design and analysis of the imager optical assembly including the spectrograph Re-Imaging Optics (RIO) which transfers the beam path from the imager focal plane to the IFS slicer module and lenslet array. Each imager component and the first two RIO mechanisms are assembled and individually aligned on the same optical plate. Baffling suppresses background radiation and scattered light, and a pupil viewing camera allows the imager detector to focus on an image of the telescope pupil. The optical plate mounts on an adapter frame for alignment of the overall system. The imager and RIO will be characterized in a cryogenic test chamber before installation in the final science cryostat.
