Radiation Angle

In Fiber optics, half the Vertex Angle of the cone of Light emitted at the exit face of an optical fiber.

Note: The cone boundary is usually defined (a) by the angle at which the far-field irradiance has decreased to a specified fraction of its maximum value or (b) as the cone within which there is a specified fraction of the total radiated power at any point in the FAR field. Synonym output angle.
