will be a fiber fed echelle spectrograph with a white pupil setup. Detailed characteristics of PLATOSpec are summarized in Table 1 below. The spectrograph will be optimised for better sensitivity in blue wavelengths to provide a good monitoring window for Ca H&K lines to investigate stellar activity.
