NIRCam wrapped up in 2013 NIRCam being installed in 2014. NIRCam (Near-InfraRed Camera) is an instrument aboard the James Webb Space Telescope.It has two major tasks, as an imager from 0.6 to 5 μm wavelength, and as a wavefront sensor to keep the 18-section mirrors functioning as one.
The Near Infrared Camera and Multi-Object Spectrometer (NICMOS) is a scientific instrument for infrared astronomy, installed on the Hubble Space Telescope (HST), operating from 1997 to 1999, and from 2002 to 2008. Images produced by NICMOS contain data from the near-infrared part of the light spectrum.
The NIRSpec (Near-Infrared Spectrograph) is one of the four scientific instruments flown on the James Webb Space Telescope (JWST). [2] The JWST is the follow-on mission to the Hubble Space Telescope (HST) and is developed to receive more information about the origins of the universe by observing infrared light from the first stars and galaxies.
FGS/NIRISS ETU, 2016 FGS Test unit undergoes cryogenic testing, 2012 Infographic of JWST instruments and their observation ranges of light by wavelength. Fine Guidance Sensor and Near Infrared Imager and Slitless Spectrograph (FGS-NIRISS) is an instrument on the James Webb Space Telescope (JWST) that combines a Fine Guidance Sensor and a science instrument, a near-infrared imager and a ...
Some definitions also include the short-wavelength infrared band from 1400 nm up to the water absorption band at 2500 nm. [2] VNIR multi-spectral image cameras have wide applications in remote sensing and imaging spectroscopy. [3] Hyperspectral Imaging Satellite carried two payloads, among which one was working on the spectral range of VNIR. [4]
Near infrared (NIR), 750–900 nm, is used primarily for imaging vegetation. Mid-infrared (MIR), 1550–1750 nm, is used for imaging vegetation, soil moisture content, and some forest fires . Far-infrared (FIR), 2080–2350 nm, is used for imaging soil, moisture, geological features, silicates, clays, and fires.
The infrared camera instrument integrated with ISIM passed its thermal tests in early 2016. [4] ISIM underwent intense thermal cold testing in late 2015 to early 2016. [5] NIRcam is extremely important to JWST, because it is not only a sensitive infrared camera, but it is also used to adjust the alignment of the main mirror segments. [4]
In infrared photography, the photographic film or image sensor used is sensitive to infrared light. The part of the spectrum used is referred to as near-infrared to distinguish it from far-infrared, which is the domain of thermal imaging.
