Multiplexing 32,000 spectra onto 8 detectors: the HARMONI field splitting, image slicing and wavelength selecting optics

Abstract:

HARMONI, the High Angular Resolution Monolithic Optical and Near-infrared Integral field spectrograph is one of two first-light instruments for the European Extremely Large Telescope. Over a 256x128 pixel field-of-view HARMONI will simultaneously measure approximately 32,000 spectra. Each spectrum is about 4000 spectral pixels long, and covers a selectable part of the 0.47-2.45 μm wavelength range at resolving powers of either R=4000, 10000, or 20000. All 32,000 spectra are imaged onto eight ...
