A concave grating has the advantage of setting up a spectroscopic system without the need for imaging optics like concave mirrors. For this reason, concave gratings are used in a wide range of applications.
Compared with plane gratings, they offer one important advantage: they provide the focusing (imaging) properties to the grating that otherwise must be supplied by separate optical elements.
