To allow mid-infrared observations within the JWST, the MIRI instrument has an additional cooling system. It works roughly similar to how most refrigerators or an air-conditioner works: a fluid is brought down to a cold temperature in the warm section, and sent back to the cold section where it absorbs heat, then it goes back to the condenser.
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
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.
Infrared Camera and Spectrograph (IRCS) Used in conjunction with the new 188-element adaptive optics unit (AO188), mounted at the infrared Nasmyth focus. Cooled Mid Infrared Camera and Spectrometer (COMICS) Mid-infrared camera and spectrometer with the ability to study cool interstellar dust, mounts on the Cassegrain focus. Decommissioned in ...
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.
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.
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 ...
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.
