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 The cardinal points lie on the optical axis of the optical system. Each point is defined by the effect the optical system has on rays that pass through that point, in the paraxial approximation. The paraxial approximation assumes that rays travel at shallow angles with respect to the optical axis, so that and .

WebThe focal plane of a lens is defined as the plane where the light from an object come into focus. When you hear of a lens having a focal length of f mm, this means that for an object very far away (infinity), the lens will form an image of that object that is f mm away.
