摘要：

The Near-Infrared Imager (NIRI) for the Gemini North telescope is now undergoing acceptance testing. NIRI is the main near-infrared facility camera on the Gemini North telescope and is designed to fully exploit the excellent characteristics of the site and the expected high performance of the telescope. NIRI offers 3 different pixel scales for wide-field, tip-tilt corrected and diffraction-limited imaging. It is equipped with a pupil imaging system to evaluate the telescope emissivity and to optimize the alignment of the instrument with the telescope. NIRI has an infrared wavefront sensor so that tip-tilt and focus corrections can be obtained even in dark cloud regions or during daytime observing.
