Target entity: Imaging IR Spectrometer
Context triple: [Chandrayaan-2, instrumentsOnOrbiter, Imaging IR Spectrometer]

A. Mid-Infrared Instrument
The Mid-Infrared Instrument (MIRI) is a key James Webb Space Telescope payload that provides imaging, spectroscopy, and coronagraphy in the mid-infrared range to study cold, distant, and dust-obscured cosmic objects.
B. Fourier transform spectrometer
A Fourier transform spectrometer is an optical instrument that measures the spectrum of a light source by recording an interference pattern and mathematically transforming it to obtain high-resolution spectral information.
C. Near Infrared Imager and Slitless Spectrograph
The Near Infrared Imager and Slitless Spectrograph (NIRISS) is a James Webb Space Telescope instrument designed for high-sensitivity near-infrared imaging and spectroscopy, particularly suited for exoplanet characterization and studies of distant galaxies.
D. MMIRS (Magellan/MMT Infrared Spectrograph)
MMIRS (Magellan/MMT Infrared Spectrograph) is a near-infrared imaging spectrograph designed for the Magellan and MMT telescopes to study faint astronomical objects at infrared wavelengths.
