MIRI is a camera and a spectrograph that observes mid to long infrared radiation from 5 to 28 microns. [1] It also has coronagraphs, especially for observing exoplanets. [2] Whereas most of the other instruments on Webb can see from the start of near infrared, or even as short as orange visible light, MIRI can see longer wavelength light. [1]
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 ...
Here is a list of currently existing astronomical optical interferometers (i.e. operating from visible to mid-infrared wavelengths), and some parameters describing their performance. Current performance of ground-based interferometers
Integrated Science Instrument Module (ISIM) is a component of the James Webb Space Telescope, a large international infrared space telescope launched on 25 December 2021. [1] ISIM is the heart of the JWST, and holds the main science payload which includes four science instruments and the fine guidance sensor.
An infrared detector is a detector that reacts to infrared (IR) radiation. The two main types of detectors are thermal and photonic ( photodetectors ). The thermal effects of the incident IR radiation can be followed through many temperature dependent phenomena. [ 2 ]
The Infrared Spatial Interferometer (ISI), run by an arm of the University of California, Berkeley, is an array of three 1.65 meter telescopes operating in the mid-infrared. The telescopes are fully mobile and their current site on Mount Wilson allows for placements as far as 70 meters apart, giving the resolution of a telescope of that diameter.
The Infrared Spatial Interferometer (ISI) is an astronomical interferometer array of three 1.65 m (5 ft 5 in) telescopes operating in the mid-infrared. [1] The telescopes are fully mobile and their site on Mount Wilson allows for placements as far as 70 m (230 ft) apart, giving the resolution of a telescope of that diameter.
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.
