GMOS
Gemini North
Optical
The two Gemini Multi-Object Spectrographs (GMOS), one on each telescope, provide 0.36-1.03 µm long-slit and multi-slit spectroscopy and imaging over a 5.5 square arcminute field of view. Each GMOS is also equipped with an Integral Field Unit (IFU) making it possible to obtain spectra from a 35 square arcsecond area with a sampling of 0.2 arcseconds. The Nod-and-Shuffle mode, which enables superior sky subtraction, is available with both GMOS-N and GMOS-S in most spectroscopic modes.
