A concave grating has the advantage of setting up a spectroscopic system without any imaging optics like concave mirrors. For this reason, the concave grating is used in a wide range of applications, such as analytical instruments, optical communications, biotechnology, and medical instruments. Spectroscopes incorporating concave gratings are classified roughly into two categories: polychromators or monochromators. holographic concave gratings are recorded on spherical substrates, with equidistant and parallel grooves.
