![F-number - Wikipedia, the free encyclopedia]()
en.wikipedia.orgIn optics, the f-number (sometimes called focal ratio, f-ratio, f-stop, or relative aperture[1]) of an optical system is the ratio of the lens's focal length to the diameter of the entrance pupil.[2] It is a dimensionless number that is a quantitative mea瀏覽：816
