The Hyperspectral Thermal Emission Spectrometer (HyTES) has 512 pixels cross-rack with pixel sizes in the range of 5 to 50 m depending on aircraft flying height and 256 spectral channels between 7.5 and 12 micrometers in the thermal infrared part of the electromagnetic spectrum.

The HyTES design is built upon a Quantum Well Infrared Photodetector (QWIP) focal plane array (FPA) , a cryo-cooled Dyson Spectrometer and a high-efficiency, concave blazed grating, produced using E-beam lithography.

HyTES is useful for a number of applications, including high-resolution surface temperature and emissivity measurements and volcano observations. HyTES was developed originally to support the Hyperspectral Infrared Imager (HyspIRI) mission and is currently supporting science data products for future ESA missions as well as NRC 2017 decadal survey missions and Surface Biology and Geology (SBG).
