The more the curvature, the more is the power. When a lens has curved surfaces on both sides, then their curvatures can be considered positive for the lens and added.
WebDec 21, 2024 · Power of Lens Formula Mathematically formula for the power of a lens is defined as: Power (P) = 1 / Focal Length (f) P = 1 / f For instance, if the focal length of a lens is 15 cm, we get 0.15 m when we translate it to meters. Take the reciprocal of 0.15 to get the power of this prism, which is 6.67. As a result, the power of this lens is 6.67 D. Websimply divide the focal length into 1. Based upon the formula just presented for focal length, you simply reverse the formula. The formula is: D = 1/f – In the formula • D = Dioptric power of lens • f = focal length in meters Again, remember to adjust the formula based on mm, cm, dm, or inches. • D = 1/f = M = meters
