Abstract

ESO's Thermal Infrared Multimode Instrument, TIMMI2,in regular operation at the 3.6m telescope on La Silla, Chile,since January 2001 is equipped with a linear polarization mode which can be used in conjunction with all scientific observing modes available. A description of the polarimeter, working between 5 and 24mu m in imaging and low-resolution grism spectroscopy is given. Calibration issues and other operational aspects are described. We report first results from the final astronomical commissioning.
