Article Summary
Assembly has been completed on the Near Infrared Camera (NIRCam) that will be the primary imager on NASA’s James Webb Space Telescope (JWST) and will also act as the telescope’s wavefront sensor to allow for control of its primary mirror. NIRCam covers the infrared wavelength range of 0.6 (the edge of visible) to 5 microns (near infrared) and its focal plane assemblies (FPA) consist of 40 million pixels and are designed to operate at 35 degrees Kelvin (-396°F/-238°C).
