The spectrograph #

  • The spectrograph is a fiber fed diffraction-limited spectrograph, which makes it compact.
  • Its design is inspired from HARPS and ESPRESSO. It will be kept under vacuum and thermally controlled to make it as stable as possible.
  • The detector is a deeply depleted 4Kx4K CCD.
