The concave grating has the advantage of being able to constitute a spectroscopic system without any assistance from concave mirrors or similar types of imageforming elements. For this reason,the Concave Grating is used in a wide range of applications, such as analytical instruments,optical communications,biotechnology,and medical instruments.
