Diopter Power Formula. D (power in diopters) = 1 / f (focal length) for example. It is common to specify the dioptric power of prescription glasses, for example, whereas the focal length is usually specified for standard lenses, microscope objectives and photographic objectives. Web the lens power or diopter is defined as follows: Web a diopter is an optical unit of measurement, the reciprocal of the secondary focal length in meters, used to express the power of a. Web the si unit for optical power is the inverse metre (m −1 ), which is commonly called the dioptre (symbol: The power of a lens is defined as the reciprocal of its. Web you can use the diopter formula to determine the focal length if you already know the power of the lens. Web you can find the power of a lens if you know the focal length with the formula. Web the dioptric power is measured in units of m −1, also called diopters (dpt). Web the diopter is the unit of measure for the refractive power of a lens. That is, dividing 1000 by the focal length (in mm) of a lens yields the diopter.
