JWST MIRI field of view in the telescope focal plane. MIRI offers 4 different observing modes, including (1) imaging with 9 photometric bands, (2) coronagraphic imaging with 4 different filters, (3) low-resolution spectroscopy with a slit or slitless configuration, and (4) medium-resolution spectroscopy with 4 different IFUs.

2024年8月22日 · MIRI provides imaging and spectroscopy capabilities in the mid-infrared wavelength range of 5 to 28 microns. Astronomers rely on MIRI to study cooler objects like debris disks, which emit most of their light in the mid -infrared, and extremely distant galaxies whose light has been shifted into the mid-infrared over time.

MIRI, or the Mid-Infrared Instrument, is an instrument on the James Webb Space Telescope. [1] MIRI is a camera and a spectrograph that observes mid to long infrared radiation from 5 to 28 microns. [1]

MIRI imaging supports a small pre-defined set of subarrays for imaging bright sources or bright backgrounds without saturating the detector. The MIRI imaging detector creates subarrays using a different scheme than the near-infrared detectors that are used in other JWST instruments.

Medium-resolution spectroscopy, an observing mode for JWST's Mid-Infrared Instrument (MIRI), obtains spatially resolved spectroscopic data between 4.9 to 27.9 μm over a FOV up to 6.6'' × 7.7''.

The Mid-Infrared Instrument (MIRI) provides JWST observers with coverage of mid-infrared wavelengths from 4.9 to 28.8 μm. Imaging can be obtained with 9 broad-band filters covering the wavelength ranges from 5.6μm to 25.5 μm.

2021年5月28日 · MIRI is the mid-infrared instrument for the James Webb Space Telescope and provides imaging, coronagraphy and integral field spectroscopy over the 5-28 micron wavelength range. MIRI is one of four instruments being built for JWST.

The Mid-Infrared Instrument (MIRI) on JWST will provide direct imaging and medium resolution spectroscopy (R~3000) over the wavelength range 5 - 28.3 micron, coronagraphic imaging at 10.65, 11.4, 15.5 and 23 micron, and low resolution spectroscopy (R~100) over the wavelength range 5 - 10 micron.

MIRI is the mid-IR instrument for the James Webb Space Telescope and provides imaging, coronography and integral field spectroscopy over the 5-28μm wavelength range. MIRI is the only instrument which is cooled to 7K by a dedicated cooler, much lower than the passively cooled 40K of the rest of JWST, which introduces unique challenges.

2021年12月25日 · MIRI (Mid InfraRed Instrument) is a scientific instrument aboard the new James Webb Space Telescope (JWST), alias Webb. JWST is the successor to the Hubble Space Telescope, launched in 1990. But unlike its forerunner operating in the visible and ultraviolet portions of the light spectrum, Webb is designed to analyse infrared radiation.
