How to calculate the Horizontal and Vertical FOV (in mm)

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.

For a standard rectilinear lens, FOV = 2 arctan x 2 f, where x is the width of the film. When a photographic lens is set to "infinity", its rear principal plane is separated from the sensor or film, which is then situated at the focal plane, by the lens's focal length. dhl freight boka online

"WebOr, use Calculator #3 to determine the field of view resulting from a fixed working distance. Lenses having focal lengths of 6, 8, 12, 16, 25, 35 and 50 mm are commonly available. Using a shorter focal length lens decreases your working distance and therefore captures more light, but the resulting image will be more distorted. " - Focal length working distance field of view
