Optical efficiency formula

WebThe wall-plug efficiency of a laser system is its total electrical-to-optical power efficiency, i.e., the ratio of optical output power to consumed electrical input power as measured at the wall plug. For example, if the optical output power of a laser is 5 W while its power supply consumes 100 W of electrical power, the wall-plug efficiency is 5%. WebAug 22, 2015 · Optical efficiency. A first definition of the optical efficiency [6, 8], nopt, i, is the light power transmission efficiency through the concentrator up to the cell surface for light rays impinging at the entry aperture from a given nominal direction v (usually refer to as the normal incidence). This definition is wavelength dependent and cell ...
