The F Number or F-Stop is used to express the aperture setting of a photographic lens. More technically speaking, this number is the ratio (the mathematical division) between the focal length and the physical aperture of the lens. This number therefore has no unit.
In photography, the diaphragm is a mechanism composed of several articulated metal plates, which restricts the passage of light in the photographic lens and thus the amount reaching the digital sensor.
