                                    We present deep optical and near infrared imaging over half square
degree of sky in the centres of the ELAIS regions N1 and N2 and
coincident with deep XMM/Chandra observations. The data have been
obtained with the Wide Field Camera (WFC) and the Cambridge InfraRed
Survey Instrument (CIRSI) both at the Isaac Newton Telescope
(Observatorio del Roque de los Muchachos, Canary Islands). Limiting
magnitudes achieved are g'=26.7, r'=26.2, i'=25.0 and H=20.2 (3 sigma).
These data have been used to identify the faint optical counterparts of
the Infrared Space Observatory (ISO), radio and X-ray sources in these
areas.
