NIRCam Instrumentation

JWST Near Infrared Camera (NIRCam) instrumentation includes opticsfilters, detectors, and other hardware receiving light from the field of view to support its four observing modes.

The NIRCam science observing modes at 0.6–5.0 μm include imaging, coronagraphy, and grism wide field slitless spectroscopy, as well as specialized time-series monitoring modes. To support these modes, as well as wavefront sensing for mirror alignment, information on the NIRCam instrument hardware is available in these articles:

For wavefront sensing and mirror alignment, additional optical elements are available in the pupil and filter wheels.

The two NIRCam modules contain nearly identical sets of all of these elements.
