Webb Instruments Perfected to Microscopic Levels

Dressed in a cleanroom suit to prevent contamination, Optics Technician Jeff Gum aligns a replacement Focal Plane Assembly (FPA) with a powerful three-dimensional microscope at NASA's Goddard Space Flight Center in Greenbelt, Md. This FPA will be installed on the Near Infrared Camera (NIRCam) instrument, which has unique components that are individually tailored to see in a particular infrared wavelength range. By using the microscope, Gum ensures the FPA detectors are characterized and ready for installation onto NIRCam, the James Webb Space Telescope's primary imager that will see the light from the earliest stars and galaxies that formed in the universe.
