... Fermat’s principle can be used to derive the shape of a boundary that images light from one side of the boundary to another. This shape is a cartesian oval and is used for aspheric lenses Spherical lenses can well approximate the ideal shape of an aspherical lens for paraxial beams and are usually m ...

... Spherical aberration in lenses is an effect which produces an imperfection in the image. It happens when light being refracted from the edge of a lens is brought to a focus slightly before light from the centre of the lens. This is due to the fact that the surfaces of simple converging lenses are le ...

... 5. A lens with f = +500 mm is sawn into two pieces through a plane cutting through the optical axis (i.e., the cut is along a diameter). A point source of monochromatic light with λ0 = 500 nm is placed on the optical axis at a distance z1 = 1000 mm from the lens. The half lenses are gradually moved ...

F-number



In optics, the f-number (sometimes 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. It is a dimensionless number that is a quantitative measure of lens speed, and an important concept in photography. The number is commonly notated using a hooked f, i.e. f/N, where N is the f-number.
