A new instrument for multi-dimensional spectroscopy at the Gregory Coudé Telescope (GCT) at the Observatorio del Teide/Tenerife is presented. The system, consisting of a scanning device, a Stokes-V polarimeter and a suitable CCD system, performs fast spatial scanning. It preserves the good polarization properties of the telescope by using a Bowen compensator. We describe the instrument, the different modes of operation, and how it is controlled and give some performance data.

Key words: instruments: spectrographs; polarimeters -- Sun: general
