Focal length optics
WebFocal length definition, the distance from a focal point of a lens or mirror to the corresponding principal plane. Symbol: f See more. Generally, lenses that have fixed magnifications have fixed or limited WD ranges. While using a telecentric or other fixed magnification lens can be more constraining, as they do not allow for different FOVs by varying the WD, the calculations for them are very direct, as shown in Equation 4. (4)FOV=HmFOV=Hm Since … See more A 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 … See more In many applications, the required distance from an object and the desired FOV (typically the size of the object with additional buffer space) are known quantities.
