We present integral field spectroscopy of the double imaged quasar HE1104‐1805 taken with the optical fiber system INTEGRAL‐WYFFOS at theWHT telescope. From the spectra of the two components we have measured the continuum and line emission ratios, finding an offset between them that can be related to microlensing. (© 2004 WILEY‐VCH Verlag GmbH & Co.
