WebThe power, P, of a lens is very easy to calculate. It is simply the reciprocal of the focal length, expressed in meters P = 1 f. 16.15 The units of power are diopters, D, which are … In optics, optical power (also referred to as dioptric power, refractive power, focusing power, or convergence power) is the degree to which a lens, mirror, or other optical system converges or diverges light. It is equal to the reciprocal of the focal length of the device: P = 1/f. High optical power corresponds to short focal length. The SI unit for optical power is the inverse metre (m ), which is co…
