IGRINS-2 will be a high-resolution near-infrared spectrograph (R ~ 45,000; 1.45 - 2.50 μm), closely based on the original IGRINS (Immersion GRating INfrared Spectrograph). Unlike IGRINS, being used as a visiting instrument at Gemini South, IGRINS-2 will be a full facility instrument when it comes to Gemini North.
After successfully completing design reviews, the IGRINS-2 project is currently in the build phase led by the Korea Astronomy and Space Science Institute (KASI) in Daejeon, Korea. We are aiming for commissioning of IGRINS-2 in late 2023 and offering it to the Gemini science community in late 2024.
