Euclid is proposed to have two instruments: a wide-field visible light imager, and a near-infrared imaging photometer and slitless spectrometer:

  1. VIS:
    • visible light imager, one wavelength band 550-900 nm
    • Detectors: 36 4k x 4k CCDs, 0.5 deg2 field-of-view, 100 milliarcsecond pixels
  2. NISP:
    • near-infrared imaging photometer and slitless spectrometer
    • 16 2k x 2k HAWAII2RGs, 0.5 deg2 field-of-view, 300 milliarcsecond pixels
    • imaging photometer contains 3 filters Y, J, H in the 1-2 micron wavelength range
    • spectrometer contains 3 red and 1 blue grisms, to provide NIR spectra with multiple dispersion directions; spectral resolution λ/Δλ ~ 250 over two pixels
