WebA fixed focal length lens, also known as a conventional or entocentric lens, is a lens with a fixed angular field of view (AFOV). By focusing the lens for different working distances (WDs), differently sized field of view (FOV) can be obtained, though the viewing angle is … WebThis is sometimes also referred to as the effective focal length (v) of the system, and is true for both simple as well as complicated systems. The distance from the rear lens to the image plane is simply the back focal distance (v"). The difference between the v and v" can be found by the formula: δ = − d n f f 1 = v" - v' where n=1 in air Share WebThe distance between the exit pupil and the last optical surface (or the geometrical end of the ocular lens) is called the eye relief; it can be inconveniently small for some ocular lenses with a short focal length. … howgill beck
