Ultra–large field-of-view two-photon microscopy
... The design of the scan system begins with the selection of the objective. We seek a field-ofview that encompasses 10 mm, a numerical aperture (NA) to achieve 1-µm resolution, and a back aperture that does not exceed 25 mm. The singular choice is a 4-times magnification (f = 45 mm), 0.28 NA air-immer ...

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.
