WebThe Beam Angleis the angle between the two directions opposed to each other over the beam axisfor which the luminous intensityis half that of the maximum luminous intensity. The luminous intensities are measured in a plane normal to the nominal beam centerline. If the beam is not rotationally symmetric, then the beam angle WebThe angle of reflection \theta_r of a ray or beam is the angle measured from the reflected ray to the surface normal. From the law of reflection, \theta_i=\theta_r, where \theta_i is the angle of incidence. \theta_r is measured between the ray and a line normal to the surface that intersects the surface at the same point as the ray. See also: Angle of Incidence, … phil lancaster patriarchyIn 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.
