Descripción
Since May 2005 the Tenerife Infrared Polarimeter II (TIP-II) has been
operational at the Vacuum Tower Telescope on Tenerife. The core of the
polarimeter is a 1024×1020 pixel infrared camera allowing for high
precision measurements of the full Stokes vector with a pixel size of
0.18 arcsec, corresponding to the diffraction limit of the telescope at
1 μm. The polarimeter is able to reach a polarimetric accuracy of a
few times 10-4, covering a wavelength range of 1 to 1.8
μm. With an upgrade in July 2006, the slit size has been increased to
77 arcsec allowing most active regions to be covered with a single scan.
Here we present the technical details of the polarimeter and the camera.
We also show some data illustrating the power of this new
instrumentation.
