WebThe key is to understand that focal length is calculated by measuring the distance from the optical center of the lens to the image sensor, and this distance is measured in mm. The longer the focal length, the physically longer the lens will be. Lenses with a wider view will have a shorter focal length and are physically shorter by comparison.

WebThe field of view is the area of coverage and the degree of detail to view, as determined by the focal length of the lens and the size of the image sensor. The focal length is usually defined as the distance between the entrance lens and the point where all the light rays converge to a point (normally the camera’s image sensor). WebThe focal length of the lens describes the distance between the lens and the focused image on the sensor. As light passes through the lens it will either converge (positive focal length) or diverge (negative focal length), however within cameras the focal length is predominately positive.

WebNormally, the focusing distance is slightly larger than the working distance because working distance is measured from the front end of the lens.

WebField of view or FOV is the area of the object that is imaged by a microscope system. The size of the FOV is determined by the objective magnification. When using an eyepiece-objective system, the FOV from the objective is magnified by the eyepiece for viewing. In a camera-objective system, that FOV is relayed onto a camera sensor.
