GMTIFS Overview GMTIFS Project ETC Spectrograph ETC Imager ANU GMTO
GMTIFS will incorporate an adaptive-optics near-infrared
integral-field spectrograph (IFS) with an adaptive-optics
near-infrared imager.
Full details on the current design aspects of GMTIFS are available at the
GMTIFS web site.
GMTIFS will be fed either by the GMT Natural Guide Star or Laser
Tomography Adaptive Optics systems. Natural-seeing observations are
not excluded, but will be highly over-sampled.
