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. WebThe purpose of this experiment is to explore the relationship between working distance, field of view (FOV) and focal length, and the relative tradeoffs between short and long focal lengths. ...
