The Near-Infrared Camera (NIRCam) is one of Webb’s four scientific instruments. NIRCam is Webb’s primary near-infrared imager, providing high-resolution imaging and spectroscopy for a wide variety of investigations. Because NIRCam is the only near-infrared instrument with coronagraphic and time-series imaging capabilities, it is crucial for many exoplanet studies. In addition to imaging and spectroscopy, NIRCam is also part of Webb’s wavefront sensing and control system, which detects and corrects for slight irregularities in the shape of the primary mirror or misalignment between mirror segments, giving the telescope the ability to focus clearly on objects near and far. NIRCam was built by a team at the University of Arizona and Lockheed Martin’s Advanced Technology Center.
