Abstract

The Integral Field Spectrograph (IFS) of CHEOPS, the 2^nd generation VLT instrument for planet finding, will attain a very low resolution (R=15) in order to search for cold (and warm) planets in stellar neighbourhood. This will allow to exploit wide band integral field spectroscopy to perform differential photometry. The complete description of CHEOPS IFS is given as a separate contribution to this conference; in this paper the analysis and the project of the very low disperser are outlined.
