Lens Aberrations and Ray Tracing 1 Background
... Where would spherical aberrations be an issue? Many times an experiment will require a wellcollimated beam or focusing as much energy as possible into a point, situations that mandate minimal spherical aberrations. Which lens should be used? Bi-convex or plano convex — and in the latter case, which ...

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.
