Abstract: The new full-Stokes polarimeter implemented in the 2D ‘Göttingen’ Fabry-Perot spectrometer, based on ferroelectric liquid crystals, yields magnetograms with minimised seeing induced crosstalk. A spatial resolution of 0.″30–0.″35 is achieved after applying speckle methods. The detection limit for the magnetic field strength is 16G (≡ 3σ), yielding a polarimetric sensitivity of 7–8×1015Mx. Examples of intensity maps, Dopplergrams and magnetograms from quiet Sun are discussed.
