Concave Diffraction Gratings are different from flat diffraction gratings. They have the advantage of being able to construct a spectroscopic optical system without using imaging elements such as concave mirrors. Therefore, it should be widely used in various analytical instruments, optical communications, biology, medical equipment and other fields. Spectroscopes using concave diffraction gratings can be roughly divided into polychromators and monochromators.
