Abstract: Lens galaxies are objects of great interest in extragalactic astronomy and cosmology and were one of the first targets in the history of IFS. We will present new data obtained with INTEGRAL of some gravitational lens systems. Thanks to the very good spectral performance of INTEGRAL-WYFFOS --covering all the optical range at once-- we can discuss the extinction in the very distant lens galaxies from the visible to the UV and compare with the extinction curves in our local environment (the Milky way and the Magellanic Clouds). This study also provide an independent method for determining the redshift in a lens galaxy (dust redshift). We will also present some maps of extended line emission useful to study the host galaxy of the lensed QSO.
