WebIn a camera lens, the focal point is located on the sensor if the image is “in focus”. The Field of View (FOV) of a camera and lens is a measure of the spatial dimensions that the camera and lens can include in an acquired image. It is correctly specified in terms of the angle between the two edges of the camera image. 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), … 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. This … 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 … See more Web3 × 3 mosaic of the full optical FOV within 9 × (0.033 + 0.533) seconds = 5.1 seconds 0.566 sec for images with same physical FOV and multiple λ.
