The IGRINS is a compact high-resolution near-infrared cross-dispersed spectrograph whose primary disperser is a silicon immersion grating. IGRINS covers the entire portion of the wavelength range between 1.45 and 2.45μm that is accessible from the ground and does so in a single exposure with a resolving power of 40,000.
An improved version of the IGRINS only for the Gemini Telescope(s).
The G-CLEF is one of the first instrument for the Giant Magellan Telescope (GMT). The G-CLEF is a fiber fed, visible band echelle spectrograph that is capable of extremely precise radial velocity (goal of 10cm/s) measurement for detection of Earth-sized exoplanets orbiting a Sun-like star in its habitable zone.
The GMT Near-IR spectrograph (GMTNIRS) is a 1.1 - 5.4 micron spectrograph suitable for studies of young stellar objects, debris disks, and protoplanetary systems. This instrument will employ Silicon immersion gratings to accomplish high spectral resolution in a compact space.
The MagNIFIES is a project to bring the GMT instrument GMTNIRS to Magellan before GMT needs it. With its spectral resolution of 40,000 - 50,000 and the largest simultaneous spectral coverage (1-5 microns) of any high resolution spectrograph in the world.
Brief introduction will be written.
