The IGRINS-2 Integration Time Calculator is in development.
The Immersion GRating INfrared Spectrograph 2 (IGRINS-2) is a compact high-resolution near-IR spectrograph installed in the Cassegrain focus of the Gemini North telescope. The instrument, which concept was based on the original IGRINS design, has been developed and built by a collaboration between Korea Astronomy and Space Science Institute (KASI) and the International Gemini Observatory. It makes use of a silicon immersion grating as the main disperser and two VPH gratings as cross-dispersers. The instrument covers all of the H and K bands simultaneously with a resolving power of R ~ 45,000 and a single 3-pixel slit. The First light was achieved in October 2023 and commissioning was completed in April 2024.
