A versatile new high-throughput imager and spectrograph, ACAM, has been successfully commissioned at the William Herschel Telescope. In imaging mode, ACAM offers an 8-arcmin field of view (scale 0.25 arcsec/pixel). A set of U B V R I Z filters is available by default, but almost any of ING's broad-band or narrow-band filters can be mounted in ACAM. Low-resolution spectroscopy over ~ 3500 - 9500 A is provided by a VPH disperser. For a 1.0-arcsec slit, the on-axis spectroscopic resolutions is R ~ 450 at 6000 A. For a 0.5-arcsec slit, R ~ 900. ACAM is mounted permanently at a folded-Cassegrain focus, and can be deployed at a few minutes notice. Observing time can be applied for through the usual channels (i.e. via the national time-allocation committees, or through the ING service observing programme).
