We report Hubble Space Telescope observations of six gravitational lenses with the Advanced Camera for Surveys. We measured the flux ratios between the lensed images in seven filters from 8140 ? to 2200 ?. In three of the systems, HE0512?3329, B1600+434, and H1413+117, we were able to construct UV extinction curves partially overlapping the 2175 ? feature and characterize the properties of the dust relative to the Galaxy and the Magellanic Clouds. In HE1104?1804, we detect chromatic… CONTINUE READING
