HARMONI is the first\u2011light integral field spectrograph for the Extremely Large Telescope (ELT)<\/strong>. Designed as a workhorse instrument, it will deliver spatially resolved spectroscopy at unprecedented angular resolution<\/strong>, enabling transformative science from the Solar System to the early Universe. <\/p>\n\n\n\n

HARMONI will exploit the full potential of the 39\u2011metre ELT by combining adaptive optics with integral field spectroscopy. This unique capability allows astronomers to obtain a spectrum at every spatial position across a two\u2011dimensional field, revealing the physical, chemical and kinematic properties of astronomical objects at the finest scales.<\/p>\n\n\n\n

Science with HARMONI<\/h3>\n\n\n\n

HARMONI will address some of the most compelling questions in modern astrophysics by delivering spatially resolved spectroscopy at unmatched angular resolution.<\/p>\n\n\n\n

The instrument\u2019s capabilities are organised around six main science themes, developed and prioritised by the HARMONI Science Working Groups.<\/p>\n\n\n\n

Instrument Overview<\/h3>\n\n\n\n

HARMONI is an adaptive\u2011optics assisted integral field spectrograph operating in the near\u2011infrared. It is designed to be the primary workhorse spectrograph for the ELT at first light.<\/p>\n\n\n\n

The instrument provides multiple spatial scales and spectral resolutions, optimised for a broad range of science cases while maintaining a simplified and robust architecture.<\/p>\n\n\n\n

Consortium<\/h3>\n\n\n\n

HARMONI is developed by an international consortium of institutes in close collaboration with ESO.<\/p>\n\n\n\n

The consortium brings together expertise in instrumentation, adaptive optics, software, and science exploitation.<\/p>\n\n\n\n
