HARMONI
HARMONI is the first‑light integral field spectrograph for the Extremely Large Telescope (ELT). Designed as a workhorse instrument, it will deliver spatially resolved spectroscopy at unprecedented angular resolution, enabling transformative science from the Solar System to the early Universe.
HARMONI will exploit the full potential of the 39‑metre 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‑dimensional field, revealing the physical, chemical and kinematic properties of astronomical objects at the finest scales.
Science with HARMONI
HARMONI will address some of the most compelling questions in modern astrophysics by delivering spatially resolved spectroscopy at unmatched angular resolution.
The instrument’s capabilities are organised around six main science themes, developed and prioritised by the HARMONI Science Working Groups.
Instrument Overview
HARMONI is an adaptive‑optics assisted integral field spectrograph operating in the near‑infrared. It is designed to be the primary workhorse spectrograph for the ELT at first light.
The instrument provides multiple spatial scales and spectral resolutions, optimised for a broad range of science cases while maintaining a simplified and robust architecture.
Consortium
HARMONI is developed by an international consortium of institutes in close collaboration with ESO.
The consortium brings together expertise in instrumentation, adaptive optics, software, and science exploitation.
