Dark Energy Camera

"The Dark Energy Camera (DECam) on the Blanco 4m telescope, located at the Cerro Tololo Inter-American Observatory, will provide the optical imaging for targeting for 2/3 of the Dark Energy Spectroscopic Instrument (DESI) footprint, covering both the North Galactic Cap region at Dec ≤ 32° and the South Galactic Cap region at Dec ≤ 34°. Due to the combination of large field of view and high sensitivity from 400-1000 nm, DECam is an efficient option for obtaining photometry in the g�, r�, and z� bands."
