IGRINS (the Immersion Grating Infrared Spectrometer) is an echelle spectrometer that can provide an R=45,000 spectrum covering the entire H and K bands in a single exposure. It was built as part of a collaboration between the University of Texas (UT), the Korea Astronomy and Space Institute (KASI), and Kyung Hee University. IGRINS will explore broad scientific topics including Solar system, Stars and Stellar Systems, Star and Planet Formation, Diffuse ISM, and Galaxies.

The instrument started its normal operation at the 2.7-m Harlan J. Smith Telescope (HJST) of the McDonald observatory after a successful commission in early 2014. While IGRINS will be mainly used at HJST, it will regularly visit 4.3m Discovery Channel Telescope, Happy Jack, Arizona, starting from September 2016.
