An aperture stop refers to a physical entity that restricts the passage of light beams within an optical system. It can be the edge of a lens, a frame, or a specially designed aperture screen.
Aperture stops serve two main purposes: limiting the size of the light beam or restricting the field of view.
In optical systems, the most commonly used aperture stop for restricting light beams is called an aperture stop. It allows adjustment of the size of the light spot by altering the size of the central aperture. The size of the aperture determines how much light energy enters the reaction system.
