INGRID (Isaac Newton Group Red Imaging Device) is a near IR camera for use at the Cassegrain focus of the 4.2m WHT, but it is also the NAOMI imager at the GRACE Nasmyth focus. It was mostly built and developed at ING, and commissioned in March 2000. At the heart of INGRID is a 1024x1024 Hawaii near-IR detector array for imaging from 0.8 to 2.5 microns. The pixel scale currently is 0.238''/pixel (0.04"/pix with NAOMI), giving a total field of view of 4.06'x4.06' (~40"x40" with NAOMI). INGRID is operated with Ultradas since September 2001.

This page is intended to provide useful information for those astronomers who will be observing with INGRID, but also to introduce potential users of INGRID to her capabilities and characteristics.

INGRID home page is still in progress therefore if you require information which is not provided here (or do not have easy access) or you have suggestions for improving this web site, please mail me (azurita@ing.iac.es).
