The TSST (Tor Vergata Synoptic Solar Telescope) is a new synoptic telescope composed of $H\alpha$ telescope and Magneto Optical Filter (MOF)-based telescope in the potassium (KI D1) absorption line. $H\alpha$ observations are fundamental for the detection of flaring regions. The MOF-based telescope will moreover produce line-of-sight magnetograms and dopplergrams of the solar photosphere. Magnetograms are essential for the study of the magnetic field's geometry, while the dopplergrams can be used to study the dynamics of the solar lower atmosphere. We present the optical design of the MOF-based instrument and the preliminary spectral characterization of this instrument.
