IRCS: infrared camera and spectrograph for the Subaru Telescope

We report current status of the IR 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 micrometers . IRCS consists of two parts: one is a cross-dispersed spectrograph providing mid to high spectral resolution, the other is a near-IR camera with two pixel scales, which also serves as an IR slit-viewer for the echelle spectrograph. The camera also has grisms for low to medium resolution 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.
