Solar Multi-Channel Telescope

    Solar Multi-Channel Telescope (SMCT) at HSOS is a unique video magnetograph in the world that can simultaneously measure the solar 2-dimension magnetic field and velocity field with different spectral lines. SMCT excels in the innovative design of its Multi-Channel Filter. It can simultaneously measure Stokes parameters of different magnetically sensitive lines produced at various altitudes of solar atmosphere to get the solar magnetic field and velocity field. The field of view can be either full-disc or local active region. The profiles of spectral lines and profiles of Stokes parameters can also be scanned. In general the SMCT is a system with high sensitivity, high efficiency, high temporal and spatial resolution and mediocre spectrum resolution. Listed below are the five optical telescopes of the SMCT.
