我们描述了 Lick 自适应光学红外摄像机 (IRCAL) 的设计、特性和性能。 IRCAL 是一款 1-2.5 微米相机,经过优化,可与 Shane 3 m 望远镜上的 LLNL Lick 自适应光学系统配合使用。该相机采用金刚石车削镀金光学器件,可在整个近红外范围内提供高效的衍射极限成像。 IRCAL 结合了自适应光学、冠状掩模和用于高分辨率光谱的交叉分散硅棱镜提供的高动态范围图像的优化。
We describe the design, characterization and performance of the IR Camera for Adaptive Optics at Lick (IRCAL). IRCAL is a 1-2.5 micron camera optimized for use with the LLNL Lick adaptive optics system on the Shane 3 m telescope. Using diamond-turned gold-coated optics, the camera provides high efficiency diffraction limited imaging throughout the near- IR. IRCAL incorporates optimizations for obtaining high dynamic range images afforded by adaptive optics, coronagraphic masks, and a cross-dispersed silicon grism for high resolution spectroscopy.
