摘要：

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 1-5 mu m. 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 AO or tip-tilt to check IRCS and its interface to the telescope. We confirmed the basic imaging and spectroscopic capability we had estimated.
