The theory of formation of hydrogen lines in the presence of stationary electric and magnetic fields is applied to the calculation of the emerging Stokes profiles from a slab of hydrogen plasma, for different optical thicknesses of the slab. The calculations are performed assuming different analytical dependences of the source function on the optical depth. Typical results for hydrogen lines of interest in solar plasmas investigation are then shown.
