我们报告了斯巴鲁望远镜的红外相机和光谱仪的现状。IRCS是一款斯巴鲁设备，针对高分辨率图像进行了优化，具有自适应光学(AO)和倾斜1-5im的倾斜。红外光谱仪包括两个部分：一个是提供中高光谱分辨率(R=5,000-20,000)的交叉分散光谱仪，另一个是具有两个像素尺度(0.058，0.023角秒/像素)的近红外相机，它也是梯形光谱仪的红外狭缝观察器。该相机还具有用于中低分辨率(R=100-1,000)光谱的光栅。在这次SPIE会议前一个月，我们刚刚完成了第一次工程运行。这是一个没有AU或倾斜的初始性能评估，以检查IRCS及其与望远镜的接口。我们确认了我们估计的基本成像和光谱能力。
We report current status of the Infrared Camera and Spectrograph (IRCS) for the Subaru Telescope. IRCS is a Subaru facility instrument optimized for high-resolution images with adaptive optics (AO) and tip-tilt at 1—5im. IRCS consists of two parts: one is a cross-dispersed spectrograph providing mid to high spectral resolution (R=5,000—20,000), the other is a near-infrared camera with two pixel scales (0.058, 0.023 arcsec/pix), which also serves as an infrared slit-viewer for the echelle spectrograph. The camera also has grisms for low to medium resolution (R= 100— 1 ,000) spectroscopy. We have just completed the first engineering run about one month before this SPIE conference. It was an initial performance evaluation without AU or tip-tilt to check IRCS and its interface to the telescope. We confirmed the basic imaging and spectroscopic capability we had estimated.
