Abstract

MMT-POL is an adaptive optics optimized imaging polarimeter for use at the 6.5m MMT. By taking full advantage of the adaptive optics secondary mirror of the MMT, this polarimeter will offer diffraction-limited polarimetry with very low instrumental polarization. This instrument will permit observations as diverse as protoplanetary discs, comets, red giant winds, galaxies and AGN. We report on progress toward regular operation of MMT-POL, including early laboratory calibration and optimization. Characterization of the 1-5μm Virgo array and supporting electronics is included, as are tests of the polarimetry optics at the heart of this instrument.
