PAOLO: A Polarimeter Add-On for the LRS Optics at a Nasmyth focus of the TNG†
2014
We describe a new polarimetric facility available at the Istituto Nazionale di AstroFisica / Telescopio Nazionale Galileo at La Palma, Canary islands. This facility, PAOLO (Polarimetric Add-On for the LRS Optics), is located at a Nasmyth focus of an alt-az telescope and requires a specific modeling in order to remove the time- and pointing position-dependent instrumental polarization. We also describe the opto-mechanical structure of the instrument and its calibration and present early examples of applications. (© 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
