NASA's James Webb Space Telescope

Near-Infrared Camera (NIRCam)

The Near-Infrared Camera (NIRCam) is JWST’s primary imager in the wavelength range from 0.6 to 5 μm. It consists of two, nearly identical, fully redundant modules, which point to adjacent fields of view.

NIRCam has five observing modes: 

  1. Imaging
  2. Coronagraphic imaging
  3. Wide field slitless spectroscopy
  4. Time-series imaging (photometric monitoring)
  5. Grism-time series (spectroscopic monitoring)

NIRCam will also obtain wavefront sensing measurements used to align and phase JWST's primary mirror.

NIRCam was built by a team at the University of Arizona (UA) and Lockheed Martin’s Advanced Technology Center, led by Prof. Marcia Rieke at UA.
