Engineering view of the HARMONI spectrograph for the E-ELT
HARMONI, or the High Angular Resolution Monolithic Optical and Near-infrared Integral field spectrograph, will be one of the first-light instruments installed on the E-ELT and will function as the workhorse instrument for visible light and near-infrared spectroscopy in the wavelength range 0.5–2.4 µm.
This engineering drawing shows a cutaway view of the instrument’s complex optics.
