A new concept of polarimeter has been designed to be used together with the arrays of bolometers developed at the Max-Planck-Institut fuer Radioastronomie in Bonn. The new polarimeter has the unique characteristic of being tunable over a wide range of wavelengths and of producing a negligible absorption. It has been used at the Heinrich-Hertz telescope to measure the linear polarization of some quasars and of some extended sources inside our Galaxy. Some results are presented here. We detected polarization on the quasars 3C279 and 1633+382. On 3C279 we also detected polarization variability on a time scale of a week. We performed also maps of extended sources: the BN/KL complex in Orion OMC-1, a filament cloud in Orion OMC-3 and the massive star-forming region IRAS 05358+3543. The polarimeter has low spurious polarization and a high modulation efficiency and the tests at the telescope show that it is well suited to become a permanent facility.
