The Immersion Grating Infrared Spectrometer (IGRINS) is a near-infrared spectrometer with coverage of the near-IR H & K bands 1.45-2.5 microns with a spectral resolving power R~45000 (7 km s-1).   It is a joint collaboration between The University of Texas at Austin and the Korea Astronomy and Space Science Institute (KASI). IGRINS was commissioned in 2014 on the 2.7 m telescope at McDonald Observatory. It has traveled to the Discovery Channel Telescope (now the Lowell Discovery Telescope) and to Gemini-South. In 2024 it returned back to the 2.7 m telescope at McDonald Observatory where it currently resides.

IGRINS Status:

IGRINS is currently on the 2.7m Harlan J. Smith Telescope (HJST) at McDonald Observatory.  For more information see https://sites.google.com/view/igrinsatmcdonald/home. 

IGRINS-2 is a "twin" of IGRINS built by KASI and now commissioned as a facility instrument on Gemini North.  See https://www.gemini.edu/instrumentation/igrins-2 for more information about IGRINS-2.

The standard acknowledgement for IGRINS should be in every publication using IGRINS data:

This work used the Immersion Grating Infrared Spectrometer (IGRINS) that was developed under a collaboration between the University of Texas at Austin and the Korea Astronomy and Space Science Institute (KASI) with the financial support of the Mt. Cuba Astronomical Foundation, of the US National Science Foundation under grants AST-1229522 and AST-1702267, of the McDonald Observatory of the University of Texas at Austin, of the Korean GMT Project of KASI, and Gemini Observatory.
