WebFocal length definition, the distance from a focal point of a lens or mirror to the corresponding principal plane. Symbol: f See more. WebThe focal length of an optical system is a measure of how strongly the system converges or diverges light; it is the inverse of the system's optical power. A positive focal length indicates that a system converges light, while a negative focal length indicates that the system diverges light.
