WebIn electromagnetics, especially in optics, beam divergence is an angular measure of the increase in beam diameter or radius with distance from the optical aperture or antenna aperture from which the beam emerges. The term is relevant only in the "far field", away from any focus of the beam. WebThe angle of view is the angular size of the view cone. (See diagram above.) You might also see it referred to as the angular field of view. The overall field of view is the maximum area your sensor can capture at a given lens focal length of lens.
