Astronomical Stokes polarimeter

Imaging Stokes polarimeter based on a composite polarizing element is designed to measure the linear polarization of both point and extended celestial bodies.

Main parameters:

  • Diameter of telescopemain mirror
    1,4 m
  • Telescope aperture ratio
    1:10
  • Simultaneous determination of the Stokes parameters
    I, Q, U
  • The number of optical channels
    4
  • Field of view
    0,5 х 0,5 deg
  • The CCD size (for each optical channel)
    40 х 40 mm
  • Spectral range
    500...1000 nm
