About Aperture:
An aperture is a hole or an opening through which light travels. In an optical system, the aperture determines the cone angle of a bundle of rays that come to a focus in the image plane.
The f-number (also called focal ratio, f-ratio, f-stop, or relative aperture) of an optical system is the ratio of the lens’s focal length to the diameter of the entrance pupil.
The focal length of an optical system measures how strongly the system converges or diverges light. The amount of light captured by a lens is proportional to the area of the aperture.
Aperture Area Equations:
n = f / D
A = π (D / 2)²
A = π (f / (2 * n))²
where:
D - aperture diameter
f - focal length
n - f-number
A - aperture area
