NIRCam is an instrument aboard the to-be-launched James Webb Space Telescope, and it has two major tasks, the first is an imager from 0.6 to 5 micron light wavelength and as wavefront sensor to keep the 18-section mirrors functioning as one.[1][2] It is an infrared camera with ten mercury-cadmium-telluride (HgCdTe) detector arrays, and each array has an array of 2048 X 2048 pixels.[3][4] The camera has a field of view of 2.2 X 2.2 arc min with an angular resolution of 0.07 arcsec at 2 microns.[5] NIRcam is also equipped with coronagraphs, which helps to collect data on exoplanets near stars, really it helps imaging anything next to a much brighter object, because the coronagraph blocks that light.[6] NIRcam is housed in the Integrated Science Instrument Module

Parts of NIRCam:[7]

The builders of NIRCam are the University of Arizona and company Lockheed Martin, in cooperation with the U.S. Space agency, NASA.[8]
