A large-scale solar collector that is capable of creating highly concentrated solar energy (typically by means of an array of large curved mirrors) in order to produce extremely high temperatures at a localized site; such as, the Odello solar furnace (the world's largest solar furnace located in the eastern Pyrenees region of France).

It generates temperature in the range of 800-2500 degrees centigrade, and is used for research on solar materials and solar energy conversion.
