IGRINS-2 has passed the Production Readiness Review (PRR) in April 2021. It will be shipped to Gemini North in 2023. TBD.
IGRINS-2 Overview
IGRINS-2 is a high-resolution near-infrared spectrograph (R~40,000; 1.49-2.46um), closely based on the original IGRINS (Immersion GRating INfrared Spectrograph). IGRINS-2 will be a Gemini North facility instrument, unlike IGRINS, which is a visiting instrument at Gemini South.
After successfully completing design review, 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 IGRINS-2 commissioning in late 2023 and offering it to the Gemini science community in late 2024.
