Isaac Newton Group Red Imaging Device (INGRID)

First light: March 2000.

De-commissioned:  January 2003 (Cassegrain).

Participating organisations: Royal Greenwich Observatory, Isaac Newton Group, Astronomy Technology Centre, Instituto de Astrofísica de Canarias.

Description: INGRID (Isaac Newton Group Red Imaging Device) is a near-IR camera for use at the 4.2m WHT.  At the heart of INGRID is a 1024x1024 Hawaii near-IR detector array for imaging from 0.8 to 2.5 microns. INGRID replaces WHIRCAM. This camera is optimized for a wide field of view at relatively short wavelengths, with good performance expected up to a wavelength of 2.2 microns. INGRID was primarily deployed at the Cassegrain focus of the WHT for direct imaging at a pixel scale of 0.25 arcseconds/pixel. It is also the principal detector for the NAOMI adaptive optics system at GRACE (Nasmyth), where it provides a pixel scale of 0.04 arcseconds/pixel.
