Abstract

FeI 1.56 μm Zeeman-sensitive lines are very important and potential to measure the magnetic field of the deepest layer of the solar photosphere. The new generation polarimeter is designed and manufactured in this wavelength range. By use of the polarimeter mounted on the vertical spectrograph of the 2 m solar telescope at Kitt Peak, we can observe the Stokes I, Q, U, V parameters simultaneously. The paper presents the introduction of the near infrared polarimeter and the polarimetry of a sunspot group.
