FWHM
 
FWHM is a mathematical parameter that describes the width of a ‘bump’ on a curve. It is given by the distance between points in the curve at which the function reaches half of its maximum value.

In goniometrical measurements of light beams we use this parameter to define the full angle of the beam. A lamp emits light energy in the shape of a cone. Usually the luminous intensity is the greatest at the center of the cone and it diminishes the closer it gets to the edge of the cone. The usable portion of the cone is defined at the point where the luminous intensity falls to 50% of the candlepower at the center (maximum).
