A wide range of diffraction gratings are available on the market today. Although the basic function of all diffraction gratings is the same, the construction details can differ, and the terminology used to describe them can often be confusing or sometimes misleading.

Ventola focuses on different types of gratings, their distinguishing features, and their associated terminology. He also presents some common applications for the different types of gratings while explaining the benefits in each application.
