The MMT and Magellan Infrared Spectrograph is a wide-field near-IR imager and multi-object spectrograph built by SAO. MMIRS will be available at the f/5 focus of the MMT in 2009, and at Magellan's 6.5m Clay Telescope in 2010.

MMIRS is based on the FLAMINGOS and FLAMINGOS 2 instruments that were developed by Richard Elston and Steve Eikenberry's group at the University of Florida.

MMIRS will offer a maximum resolution of R~3000 with a 0.4 arcsec slit. The focal scale is 0.2 arcsec/pixel, providing a 6.8 by 6.8 arcmin field of view for imaging. With slit masks the field of view will be 4 by 6.8 arcmin.
