WebIrradiance is the measurement of radiant flux per unit area hitting or passing through a surface. An absolute irradiance measurement results in a spectrum that is accurate in … Weboptics prevails, the ﬁeld at any given point in space and time is the sum of the ﬁeld from every individual wave present at that point. The fact that ﬁelds can be added is called the principle of superposition. The irradiance at a point where multiple waves exist is determined from the square of the sum of the ﬁelds. 4
