The spectrometer of the Wide-field and High-resolution Solar Telescope (WeHoST) is a multi-slit-scanning spectrograph with the ability to observe solar regions up to 5 arcmin * 5 arcmin. It is equipped with a polarimeter in dual-beam setup with a continuously rotating waveplate as the polarization modulator. The users are able to carry out full Stokes Spectro-polarimetric observations simultaneously in the MgI 517.3nm and Fe I 617.3nm lines to purse well-established spectro-polarimetric studies of the magnetic structures and plasma dynamic of the solar atmosphere. In this prestation, we describe the science requirements and defining features of this spectrometer.
