NIFS provides 3D imaging spectroscopy with spectral resolving power (lambda/delta lambda) of R~5000 over a 3.0" x 3.0" image field in the Z through K-band spectral regions (0.95 to 2.40 μm). NIFS is designed to be fed by the Gemini North Adaptive Optics system, ALTAIR, hence it is possible to achieve spatially resolved spectroscopy on scales as small as 0.1" using Natural or Laser guide stars. Coronographic spectroscopy can also be performed through use of an occulting disk.
