Low Reflectance Apertures

Pinhole Aperture

The optics aperture is a hole or an opening through which light is admitted. The aperture of an optical system is the opening that determines the cone angle of a bundle of rays that come to a focus in the image plane.

Slit Aperture

Rectangular Aperture

The apertures limit the ray bundles also known as pencils of light. They deliberately limit the light admitted by the system. The aperture stop is the stop that determines the ray cone angle, or equivalently the brightness, at an image point.
