Abstract: |
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″, 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″ 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. |
