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.
