• Abstract: Here, we present a technique that predicts the radiation's distribution inany optical system. It is based on decomposing the emitting source power byassigning a fraction of the total power to each emitted ray. All kinds of power lossesin the rays' optical paths are considered. Fractioned radiation patterns are createdin the last optical system surface, each associated with a single ray. We refer tofractioned patterns as those that conform to a whole radiating pattern. Thus, theirradiance of the completely illuminated surface is calculated by adding the opticalsystem's fractioned radiation maps. This method is non-zero étendue. The resultpresented here allows for predicting the radiation patterns accurately with ahandful of equations and can help design any image and non-image-forming opticalsystems.
