Abstract

The Gemini Near-Infrared Imager (NIRI) has now been completed and is in operation at the telescope. This paper discusses the basic design of the instrument and a number of particularly interesting technical issues. NIRI offers three different pixel scales to match different operating modes of the Gemini telescope and allows polarimetric and spectroscopic observations. It is equipped with an infrared wavefront sensor to allow tip-tilt correction even in highly obscured regions.
